CHARLOTTE, N.C. -- Philadelphia Eagles starting middle linebacker Jordan Hicks suffered an ankle injury in the first half and was later ruled out for the remainder of Thursday night's 28-23 win over the Carolina Panthers.
Hicks remained in the locker room after halftime and was replaced in the lineup by second-year player Joe Walker.
An ankle injury also knocked Hicks out of the Eagles' Week 3 game against New York Giants, but he returned to play in the following game against the Los Angeles Chargers.
Hicks, a third-year player out of Texas, is one of the key players on the Eagles' defense. He has 28 tackles and a fumble recovery this season.
