Patriots coach Bill Belichick regrets playing Wes Welker in a 2009 game that left him with a torn ACL and MCL in his left knee, according to ProFootballTalk.
Part two of 'Bill Belichick: A Football Life' shows Belichick in the week before the final regular season game against the Houston Texans, as he debates which players should rest until the playoffs.
"Maybe Welker, too," he wonders. "I don't know how smart it'd be to put him in there to get lit up another eight or 10 times like he usually does."
Though Belichick is worried about Welker getting injured, he ultimately decides to play the wide receiver. The report said that he looked devastated after the game.
Welker, who led the league with 123 catches in 2009, suffered a torn ACL and MCL and didn't return until the next season.
