DAVIE, Fla. -- Miami Dolphins linebacker Joey Porter sat out practice for the second day in a row Thursday because of a sore hamstring, and he could miss a game for only the seventh time in his 11-year career.
Porter did light exercises on the side while the team practiced. Coach Tony Sparano said Porter's hamstring is improving, but it's uncertain whether he'll play Sunday against the Buffalo Bills.
"He's going to want to play," Sparano said. "I always give him the benefit of the doubt."
Porter was also bothered by the injury last week and unable to finish Sunday's game at San Diego, although he played well and had a sack.
"We got a bunch of good plays out of Joey," Sparano said. "Joey is that way. He's never going to want to miss a game."
Porter last missed a game in 2006. He would likely be replaced by Charlie Anderson, who has six career starts.
"I'm just trying to be the best backup I can be," Anderson said. "We want that guy to come back. He's a Pro Bowler."
