Cameron suffered the concussion in last Sunday's win over the Raiders. It was his third concussion in the last two years, and he will need to be medically cleared to return to practice and game action, per NFL rules. On the season, Cameron has caught 13 passes for 250 yards and one touchdown.
The 25-year-old Cameron is in his fourth season with the Browns since being a fourth-round pick out of USC in 2011.
Backups Jim Dray and Gary Barnidge are expected to fill in for Cameron. Dray has nine catches for 118 yards and a touchdown this season, while Barnidge has added five catches for 54 yards on the season for the Browns.
The Browns are No. 12 in yards and No. 16 in points this season. Quarterback Brian Hoyer has completed 57.3 percent of his passes for 1,714 yards, eight touchdowns and two interceptions. The running back trio of Ben Tate, Terrance West and Isaiah Crowell have each rushed for more than 250 yards and have combined for nine rushing touchdowns.
Cleveland is 4-3 and in fourth place in the AFC North. The Browns host the Buccaneers on Sunday at 1 p.m.
