The Browns placed Grant (Achilles) on injured reserve Wednesday.
Grant's season thus officially comes to an end after he was diagnosed with a torn left Achilles' tendon following his exit from Tuesday's practice. While the absence of Grant will be felt most in the return game, Jake Trotter of ESPN.com notes that the 29-year-old had been pushing to carve out a slot role during training camp. Demetric Felton should get the first opportunity to replace Grant as the Browns' top option on kickoff and punt returns. Expect Grant to undergo surgery at some point later this month.
