Brian Westbrook re-injured his left knee in the Philadelphia Eagles' 23-11 divisional-round victory over the New York Giants but is expected to play against the Arizona Cardinals on Sunday, the running back told ESPN's Sal Paolantonio on Wednesday.
Westbrook said he is dealing with some "extra swelling" in the knee and wouldn't practice Wednesday.
"I'm going to spend more time running in the pool to help the muscles around the knee fire up a little bit better," he said.
Westbrook finished with just 36 yards on 18 carries and had two receptions for 10 yards last weekend.
