Pough, 25, originally signed on with the Bills as an undrafted free agent out of Howard back in 2013. Unfortunately, he was unable to make the final 53-man roster coming out of the preseason.
Pough eventually caught on with the Browns in August of last year, but he was once again unable to make the cut. Cleveland later signed him to their practice squad before signing him to a future/reserve contract in December.
Barnett, 23, signed on with the Browns as an undrafted free agent out of Oklahoma State last year. He too signed a future/reserve contract with Cleveland back in December.
Neither player has appeared in an NFL game.
