"I really feel awful for Jakeem," Browns head coach Kevin Stefanski said in a Tuesdsay statement confirming an Achilles injury for Grant. "We've witnessed how hard the young man has worked since he got to our team. We all realize injuries are a part of our game, but that doesn't make it any easier to accept especially for someone that works as hard and carries himself like Jakeem."
The Browns signed Grant to a three-year deal this offseason to be their kick and punt returner; Grant, however, was also having a standout training camp as a receiver out of the slot, as well.
Grant, a Pro Bowl returner for the Chicago Bears last season, has four punt return touchdowns and two TDs off kick returns during a career that began with the Miami Dolphins in 2016.
Earlier this week, Browns special teams coordinator Mike Priefer said he thought Grant would "transform" Cleveland's return game.
The Athens, Texas native was selected in the sixth round (No. 186 overall) by the Dolphins out of Texas Tech.
