Oakland Raiders wide receiver Martavis Bryant went down with a knee injury in their loss to the Los Angeles Chargers and did not return. After the game, Jon Gruden said the team was “really concerned” about the injury.

As it turns out, Bryant suffered what might be a possible PCL tear, Ian Rapoport of NFL Network reports.

Bryant will still have to undergo an MRI to determine whether he’ll need surgery. But either way, he is expected to miss some time due to the injury.

Bryant, who caught three passes for 17 yards before leaving the game, ranks third among Raiders wide receivers with 19 catches for 266 yards this season.

The Raiders still have Jordy Nelson, Brandon LaFell, and Seth Roberts at receiver. But an extended absence for Bryant could see more playing time for the likes of Dwyane Harris and Marc Ateman, a rookie who was called up from the practice squad after the Raiders traded Amari Cooper to the Dallas Cowboys.

Bryant’s injury won’t make that much of a difference as the Raiders’ season is already in ruins. But still, Bryant could’ve used the extra playing time to showcase himself as he hits free agency this upcoming offseason. His stock has taken a significant hit over the past few months and could’ve used the opportunity to rehabilitate it in Oakland.
