FAYETTEVILLE Arkansas will be without its leading tackler for the rest of the season.

Coach John L. Smith said linebacker Alonzo Highsmith will be sidelined because of a foot injury requiring surgery. Highsmith was injured during the first half of the 24-7 win at Auburn last Saturday. He entered the game tied for the Southeastern Conference lead in tackles (51) and had three more last Saturday before his injury.

"We cant afford any injuries, but particularly at that spot and what has taken place," Smith said. "Were going to have to bump some guys around to kind of fill that void a little bit. Because as you look at it, youre without your two starters there in being Tank (Wright) and Highsmith."

The injury ends Highsmith's career with the Razorbacks. The senior, who transferred from Phoenix (Ariz.) College before the 2011 season, had 134 tackles in 19 games.

Freshman Otha Peters and senior Terrell Williams played most of the Auburn game at linebacker last Saturday. Smith said Arkansas would have to shuffle some players around to help with depth without Highsmith, mentioning reserves Jarett Lake and Matt Marshall.

"Its tough to see one of our senior captains go out like that," Arkansas defensive end Chris Smith said. "But he came back on the sideline later in the third quarter. Hes still being a vocal leader. Its tough to lose a guy like that, but you know, other guys have to step up."
