AUC can confirm Auburn sophomore DE Carl Lawson, expected to be a key contributor in 2014, had surgery on his left knee Friday. A source close to the family said Lawson is focused on rehab and returning to the field this fall.

The specific injury was not immediately known.

Auburn has released no information regarding this matter. Often, Tigers coach Gus Malzahn addresses injuries once the prognosis is clear.

Lawson was injured in April during spring practice.

Originally, it was thought there was no significant damage to the knee.

As a true freshman in 2013, Lawson was a 247Sports and Sporting News Freshman All-American after recording 20 tackles, 7.5 for loss.
