Brown left Sunday's game against the Jaguars with a knee injury.
Just before halftime, Brown was slow to get to his feet following a hit, and he didn't take the field for the second half, instead remaining in the locker room. If he's unable to return, he'll finish Week 9 with two catches (on four targets) for 36 yards. DeVonta Smith, Jahan Dotson, Ainias Smith and Johnny Wilson are the current healthy wide receivers for the Eagles.
