Browns defensive tackle Trevon Coley will be "out for a little while" with a high-ankle sprain.
Coley, who started 15 games last season, did not participate in Friday's intrasquad scrimmage after suffering the injury the day before. It's unclear when he'll return to action.
"It's going to take him a little time, it is," head coach Hue Jackson said. "That's part of it. Well get him back I know that."
Coley is Cleveland's second starter to suffer a significant injury this week; right guard Kevin Zeitler will miss an undisclosed amount of time with a calf injury.
Without Coley, veteran Jamie Meder, second-year standout Larry Ogunjobi and former undrafted free agent Jeremy Faulk took first-team reps with the defense.
Coley, an undrafted free agent out of FAU and former practice squad member, was the surprise story of Cleveland's training camp a year ago. He finished 2017 with 41 tackles, two sacks and a fumble recovery.
