The Browns will also be missing starting linebacker Barkevious Mingo, who missed practice this week with a shoulder injury.
Cameron, who caught 80 passes for 917 yards and seven touchdowns last season, hurt his shoulder during training camp and then re-injured last week after making a 47-yard reception against Pittsburgh. Cameron did not practice this week.
Jabaal Sheard will start in place of Mingo, a first-round draft pick in 2013.
