AUBURN, Alabama — Auburn backup center Casey Dunn, who started the last two games, will miss Auburn's trip to Arkansas due to injury.

The announcement was made Tuesday by Auburn coach Gus Malzahn.

Marquel Harrell stepped in at left guard with Casey Dunn injured in the second half of the LSU game last week. Austin Golson has had to play five different positions, including the center spot.

"Casey's a tough guy," Malzahn said. "He was begging to go back in. We got him back in the game and he showed a lot of guts and a lot of courage. Just couldn't finish the thing, but he's a winner. He's a real tough guy."

Starting left guard Mike Horton might also miss the trip to Arkansas because of injury.

"We'll see where he's at," Malzahn said.
