"That's huge," defensive coordinator Sean McDermott said. "We have that big body back inside from a performance standpoint, but also from a leadership standpoint."
"There's not a thing that changed with Kevin Kolb," Reid said Wednesday, amidst a move that sparked reaction from players and fans alike. "This was all about Michael Vick and the way he has played the game. It's that simple. He has played as outstanding as any quarterback in the league to this point.
"He exceeded even my expectation. Kevin Kolb has a bright, bright future. My feelings about Kevin haven't changed one bit. But Michael has surprised all of us with his play."
Vick has thrown for 459 yards and three touchdowns, run for 140 yards, and posted a completion percentage of 63.8 and passer rating of 105.5 in 1½ games. He has yet to throw an interception.
Durant missed practice all week and had been wearing an air cast. Second-year player Russell Allen is expected to replace Durant in the starting lineup.
Safety Anthony Smith (turf toe) and kickoff returner Deji Karim (thumb) are questionable. Both missed last week's game.
