Brown was out of the lineup on Saturday and Sunday, but he started on Tuesday. He was pulled after nine innings of Tuesday's 9-5, 10-inning loss to the Mets after manager Charlie Manuel apparently saw him laboring when fielding a ball in the left-field corner.
General manager Ruben Amaro Jr. said on Wednesday that he does not view Brown's knee soreness as a long-term injury.
"I know he wants to play," Amaro said. "But it's that fine line between wanting to play and making sure it doesn't affect the team. Team's always first. We do want to see Brownie play. We do want to have him play, because I think he's going to contribute to our club. But at the same time, I want to make sure he's doing it in a healthy way."
