Starting linebacker and captain Christian Kirksey was placed on injured reserve Saturday morning with a chest injury.
A decision hasn’t been made whether he’ll have surgery following the injury suffered Monday night in the 23-3 win over the Jets. He’ll have to miss at least eight games by going on IR.
Undrafted rookie linebacker Willie Harvey (5-foot-11, 230 pounds) was promoted from the practice squad. He went to Iowa State and spent preseason with the team.
In addition to Kirksey being out, veteran linebacker Adarius Taylor is questionable with an ankle injury for Sunday night’s game against the Rams.
The Browns have dealt with a number of injuries this week.
Tight end David Njoku was placed on the IR on Friday with a broken wrist, and none of the starting secondary practiced Friday.
Rookie fifth-round pick Mack Wilson is expected to replace Kirksey in the starting lineup. Kirksey was voted a season-long captain by teammates and had 11 tackles in two games.
Kirksey, a third-round pick in 2014, had never missed a game until last season, when he ended the year on IR with a hamstring injury.
The Browns also re-signed running back Elijah McGuire to the practice squad.
Defensive end Myles Garrett is racking up the sacks — and the fines. Garrett leads the league with five sacks through two games and has been fined three times.
The league hit Garrett with two $21,056 fines for two roughing the passer penalties against the Jets. He was fined $10,527 last week for striking Titans tight end Delanie Walker in the face mask in the opener, bringing his total to $52,639.
** Rookie linebacker Mack Wilson was fined $28,075 for leading with his helmet on a tackle against the Jets.
** Jets safety Jamal Adams was docked $21,056 for a late hit on Baker Mayfield.
