The hope is that a recent procedure fixes that.
According to Ian Rapoport of NFL Network, Brown had surgery recently to remove a screw from a previous foot surgery. He’s expected to be fine by the start of training camp.
Brown’s college career ended because of a Lisfranc injury, and he seemed to hit the rookie wall late in his first NFL season. He missed two games, but he still caught 46 passes for 584 yards and seven touchdowns last season, as he was learning on the fly.
