From Comcast SportsNetEDEN PRAIRIE, Minn. (AP) -- Playing in the season opener has been at the forefront of Adrian Peterson's mind almost since he went down with a torn left ACL in the second-to-last game of the 2011 season.How long it has taken other running backs to return from the injury doesn't concern Peterson. The Minnesota Vikings' star running back has always seen himself as different from everyone else, and he has made it abundantly clear that he expects to play against Jacksonville on Sunday.He has one more week to make his case to Vikings coach Leslie Frazier and his staff.Frazier said on Monday that the Vikings would not make a decision on Peterson's status until game day, and he cautioned that even if Peterson does return, he shouldn't expect the workload he carried before he was injured just yet."We recognize if he's able to get in this first ballgame, it'll be with limited exposure," Frazier said. "We'll talk about it as the week goes on and see how he's doing and if it's even a viable option to let him play."That means fewer carries than Peterson is used to getting as the workhorse and focal point of the Vikings' offense, and likely more work for backup Toby Gerhart.Perhaps the biggest obstacle the Vikings have in handling the situation is Peterson's state of mind. He has worked tirelessly to get himself prepared to help his team, throwing himself into the rehab process from the moment he came out of surgery. With his team coming off a disastrous 3-13 season, Peterson knows they need him in the backfield to have any chance, and the coaches know it, too."You really have to take the emotion out of it," Frazier said. "You have to really hone in on what's best for him, what's best for our team. Adrian is not just another guy on our team. He is in so many ways the face of what we try to do. We have to be able to see the big picture when it comes to him and that's the way we'll approach it."On a rebuilding team coming off of a last-place finish in one of the strongest divisions in the league, the Vikings may not need to rush him back. He felt like he was ready to play in the preseason, but coaches and the team's training staff preferred to take a more gradual approach."I'd love to have him out there, that goes without saying for our entire team," center John Sullivan said. "But at the same time it's out of our hands. I hope he is. But if not, we've got to go forward with the guys that are ready to go."Peterson wasn't available for comment Monday, but he did participate in practice. Coaches will be especially interested to see how he handles himself in Thursday's padded practice."We have to see him get through some things and see how he handles certain things from a mental and physical standpoint," Frazier said. "It's different when there is no endpoint, in his case he knew a few weeks ago he wasn't going to play in the preseason. Now the mindset changes a little bit and we have to see how he handles that."Gerhart emerged as a capable fill-in for Peterson after the injury, the kind of physical runner who gets better as the game goes on and the carries increase. Gerhart had just 24 carries in the first 10 games last season, but his work load increased over the final six games as the Vikings faded from contention.As the carries increased, Gerhart's production did as well. He rushed for 91 yards on 21 carries and caught eight passes for another 42 yards against Denver on Dec. 4, then picked up another 90 yards on 19 carries the following week against Detroit.Peterson went down two weeks later in Washington and Gerhart came through with 11 carries for 109 yards, the first time he's topped 100 yards in a game in his two NFL seasons, and showed that he is up to the task in the NFL."With Toby we can run our offense even if Adrian isn't in there," Frazier said. "We feel like we don't have to change any of our plays. We're very confident and comfortable with Toby being our lead back if that's the case. The same runs that Adrian would have would be the same runs that Toby would have."NOTES:CB Josh Robinson (concussion) and S Mistral Raymond (back) returned to practice after missing the preseason finale. Frazier said they should be ready to play on Sunday. The only player whose chances are questionable right now appears to be backup LB Marvin Mitchell, who has a high ankle sprain. ... The Vikings signed OL Kevin Murphy, DL Ernest Owusu, WR Tori Gurley and WR Chris Summers to the practice squad.
PHOENIX - Major League Baseball intends to push forward with the process that could lead to possible rule changes involving the strike zone, installation of pitch clocks and limits on trips to the pitcher's mound. While baseball Commissioner Rob Manfred expressed hope the ongoing process would lead to an agreement, he said clubs would reserve the right to act unilaterally, consistent with the rule-change provision of the sport's labor contract.
Union head Tony Clark said last weekend he did not foresee players agreeing to proposed changes for 2017. Under baseball's collective bargaining agreement, management can alter playing rules only with agreement from the union - unless it gives one year notice. With the one year of notice, management can make changes on its own.
"Unfortunately it now appears that there really won't be any meaningful change for the 2017 season due to a lack of cooperation from the MLBPA," Manfred said Tuesday during a news conference. "I've tried to be clear that our game is fundamentally sound, that it does not need to be fixed as some people have suggested, and I think last season was the kind of demonstration of the potential of our league to captivate the nation and of the game's unique place in American culture."
Yet, he also added: "I believe it's a mistake to stick our head in the sand and ignore the fact that our game has changed and continues to change."
Manfred said while he prefers an agreement, "I'm also not willing to walk away." He said he will send a letter to the union in the coming days and plans to continue dialogue with Clark and others in hopes of reaching agreement.
Clark met with Cactus League teams last week, five at a time over Thursday, Friday and Saturday, before departing Monday for Florida to visit each Grapefruit League club - and proposed rules changes were a topic.
"I have great respect for the labor relations process, and I have a pretty good track record for getting things done with the MLBPA," Manfred said. "I have to admit, however, that I am disappointed that we could not even get the MLBPA to agree to modest rule changes like limits on trips to the mound that have little effect on the competitive character of the game."
Clark saw talks differently.
"Unless your definition of `cooperation' is blanket approval, I don't agree that we've failed to cooperate with the commissioner's office on these issues," he wrote in an email to The Associated Press. "Two years ago we negotiated pace of play protocols that had an immediate and positive impact. Last year we took a step backward in some ways, and this offseason we've been in regular contact with MLB and with our members to get a better handle on why that happened. I would be surprised if those discussions with MLB don't continue, notwithstanding today's comments about implementation. As I've said, fundamental changes to the game are going to be an uphill battle, but the lines of communication should remain open."
Clark added "my understanding is that MLB wants to continue with the replay changes (2-minute limit) and the no-pitch intentional walks and the pace of game warning/fine adjustments."
Manfred said he didn't want to share specifics of his priorities for alterations.
"There's a variety of changes that can be undertaken," Manfred said. "I'm committed to the idea that we have a set of proposals out there and we continue to discuss those proposals in private."
MLB has studied whether to restore the lower edge of the strike zone from just beneath the kneecap to its pre-1996 level - at the top of the kneecap. Management would like to install 20-second pitch clocks in an attempt to speed the pace of play - they have been used at Triple-A and Double-A for the past two seasons.
Players also have been against limiting mound meetings. The least controversial change appears to be allowing a team to call for an intentional walk without the pitcher having to throw pitches. In addition, MLB likely can alter some video review rules without the union's agreement- such as shortening the time a manager has to call for a review.
"Most of this stuff that they were talking about I don't think it would have been a major adjustment for us," Royals manager Ned Yost said.
Manfred said starting runners on second base in extra innings sounds unlikely to be implemented in the majors. The change will be experimented with during the World Baseball Classic and perhaps at some short-season Class A leagues. Manfred said it was a special-purpose rule "beneficial in developmental leagues."
Manfred also said Tuesday that a renovated Wrigley Field would be a great choice to host an All-Star Game and Las Vegas could be a "viable market for us."
"I don't think that the presence of legalized gambling in Las Vegas should necessarily disqualify that market as a potential major league city," Manfred said.
