Browns Place WR Andrew Hawkins on IR, Sign ILB Jayson DiManche

Concussions have claimed another victim to injured reserve, as the team officially placed WR Andrew Hawkins on the list Wednesday, ending his season.

Hawkins last played in Week 10 against the Pittsburgh Steelers, and that was his first game back from his first concussion of the season. Against the Steelers, Hawkins was on the receiving end of a cheap shot after an interception, resulting in another concussion. His season ends with him logging 27 catches for 276 yards in 8 games. Last year, in 15 games, he had 63 catches for 824 yards and 2 touchdowns. The fact that Hawkins won't be back in 2015 explains why the club re-signed WR Darius Jennings to their 53-man roster on Tuesday.

Taking Hawkins' place on the roster is ILB Jayson DiManche. 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 and was on the Chiefs' practice squad until mid-October, when the Browns signed him. He was waived in mid-November, but was on the team's practice squad before getting this most recent call-up.

Taking DiManche's spot on the practice squad is OL Conor Boffeli (6-4, 295 lbs), an undrafted free agent in 2014 out of Iowa. He has previously spent some time on the offseason roster or practice squads of the Vikings and Bears.
