Browns coach Mike Pettine said he doesn't think the shoulder issue is chronic. Cameron first injured the shoulder in training camp.
Cameron said he underwent an MRI and that there was no structural damage. His status for Sunday's game against the New Orleans Saints is unclear.
The 26-year-old caught 80 passes for 917 yards and seven touchdowns last season. He is in his fourth season with Cleveland after the team drafted him in the fourth round out of USC in 2011.
