Even though the regular season is almost over, the Patriots continue to feel out the available talent in the market. Four players were in Foxboro for tryouts Friday:
Defensive end Jason Vega, 25, a Brockton native and Northeastern grad who played the last two seasons for the Canadian Football League's Winnipeg Blue Bombers.
Wide receiver Isaiah Williams, 25, who was released by the Cardinals on Nov. 15. Williams, who played college football at Maryland, also has played for the Ravens, Steelers and Seahawks.
Wide receiver Shawn Gore, 25, a Toronto native and a three-year veteran of the Canadian Football League. He was in Green Bay's training camp in 2010.
Linebacker Nic Harris, 26, who played collegiately at Oklahoma. He appeared in 15 games (two starts) for the Bills in 2009 and 15 more for the Panthers in 2010. He was released by Carolina prior to the 2011 season.
