The Browns have signed tight end Gerell Robinson after Pro Bowler Jordan Cameron re-injured his right shoulder in Sunday's loss at Pittsburgh.

Robinson, who is in his first season from Arizona State, had been on Denver's practice squad. The team also signed wide receiver Ifeanyi Momah (if-AH-nee MOE-ma) to the practice squad.

Also, suspended wide receiver Marlon Moore has been added to the active roster. To make room, the team waived offensive lineman Ryan Seymour and terminated the contract of defensive back Aaron Berry. Linebacker Justin Staples was released from the practice squad.

The Browns have not provided an update on Cameron, who got hurt while making a 47-yard reception in the first quarter. He's been slowed by the shoulder all summer.

Cameron had a breakout season last year with 80 catches for 917 yards and seven touchdowns.
