Advocate staff photo by TRAVIS SPRADLING -- LSU head coach Les Miles shouts toward players on the field after an unsportsmanlike conduct penalty against LSU with 1:07 in the game put LSU at a big disadvantage after getting close to scoring a touchdown, Saturday, Nov. 8, 2014 in Baton Rouge. They settled for a tying field goal linstead after the 15-yard penalty. LSU lost 20-13 in overtime.

Center Elliott Porter will not play in LSU’s game at Texas A&M, coach Les Miles said Monday.

Porter injured his ankle during the loss at Arkansas and will be replaced in the starting lineup by right guard Ethan Pocic. Evan Washington will start in place of Pocic at right guard for the Tigers (7-4, 3-4 Southeastern), Miles said.

Porter, a senior from Waggaman, has started nine straight games since missing the first two while serving a suspension. Pocic started at center in the first two games.

Miles said he’s “uncertain” if Porter will miss LSU’s bowl game.

Washington, a fifth-year senior, started the first SEC game of his career in the 17-0 loss at Arkansas, replacing Vadal Alexander at left guard. Alexander, who injured his hand in the loss to Alabama, will return for the game against the Aggies (7-4-3-4), Miles said.

- LSU cornerback Dwayne Thomas, out for the season with an anterior cruciate ligament he suffered against New Mexico State, could return to the team for spring practice, Miles said. Miles said Thomas’ rehabilitation is going well and that he “hopes” he can return for spring.
