Philadelphia Eagles quarterback Michael Vick (7) throws a pass during practice at the team's NFL football training facility, Thursday, Jan. 6, 2011, in Philadelphia. The Eagles host the Green Bay Packers in a first round playoff game on Sunday.

GREEN BAY, Wis. — Green Bay Packers coaches didn't take any unorthodox measures to simulate the speed and elusiveness of Philadelphia Eagles quarterback Michael Vick this week.

Packers defensive coordinator Dom Capers says backup quarterback Matt Flynn played Vick's role in practice as the team prepared for Sunday's playoff game at Philadelphia. While Flynn doesn't have Vick's athleticism, Capers thought it was more important for his defense to face somebody who can throw the ball.

The Packers are confident on defense and think they can stop just about anybody. But they have a healthy respect for Vick's ability and know they're in for a long day, win or lose.

Defensive lineman Ryan Pickett says it is "not fun" chasing Vick around.
