Packers running back Ryan Grant injured his ankle in the second quarter against the Eagles on Sunday and didn't return. "We have five running backs and we have three that primarily do the running," Green Bay coach Mike McCarthy said. "It's the NFL and injuries are part of your journey. We had a number of guys go down. We'll regroup and we'll see where we are and be ready for Buffalo." Grant hasn't missed a start since becoming the team's featured running back in November of 2007. "For me, if you look at my track record, I would say yes," he said of playing next weekend. "But we'll take it one day at a time. "It's kind of frustrating. I want to go back in the game and help my guys. That's just the nature of what I want to do. But it happens so we have to move on. I'm going to do everything, trust me, to get my butt back on that field to help this team win."
