DiManche began his career as an undrafted free agent with the Cincinnati Bengals in 2013. In his two years with the Bengals, DiManche logged 28 tackles. He started one game in 2014 against the Indianapolis Colts, a game in which he logged 7 tackles. He was in camp when the Bengals this year, but didn't make the team's final cut. The Chiefs had just signed him to their practice squad last week.
The Browns needed another inside linebacker since ILB Craig Robertson has been hurt the past couple of weeks. They've been trying to get by with ILB Tank Carder playing a role on defense, but the team prefers to use him on special teams. Rookie ILB Hayes Pullard is still on the practice squad, but the team obviously didn't want to bring him up yet. I wouldn't be surprised if DiManche plays some snaps on defense this week, with Carder focusing on special teams again.
With RB Robert Turbin debuting this past Sunday, the Browns did not need a fourth running back on the roster any more, so Draughn was expendable.
In another move, the Browns signed TE Brian Leonhardt to the practice squad and released DB Ty Zimmerman from the practice squad.
