The NCAA has granted Auburn offensive lineman Shon Coleman a sixth year of eligibility.

Coleman was diagnosed with leukemia in the spring of 2010 about a month after signing with the Tigers. Auburn kept his scholarship available, and Coleman signed with the Tigers a year later.

He hasn't played the past two years, which Auburn said was due to leukemia.

Tigers coach Gus Malzahn says Coleman ``has been courageous in his fight and we look forward to him returning to the football field.''

The 6-foot-6, 302-pounder from Memphis, Tenn., was one of the nation's top offensive line prospects out of high school.

Coleman received treatment at St. Jude's Children's Research Hospital in Memphis.
