Oakland is dealing with some injuries on their offensive line and Silberman has spent some time with the Raiders.
Silberman, 25, is a former sixth-round pick of the 49ers back in 2015. He lasted just over a year in San Francisco before he was waived at the start of the 2016 season.
Silberman has had brief stints with the Patriots, Raiders and Colts before signing on to the Browns’ practice squad a few weeks ago.
In 2015, Silberman was active for one game.
