Shon Coleman will forego his senior season at Auburn and enter the 2016 NFL Draft.

The 6-foot-6, 313-pound left tackle declared for the draft via Twitter on Wednesday.

"It was a very hard decision but I've decided to forego my final year and enter the NFL Draft," Coleman tweeted. "I'll forever be an Auburn Tiger!"

Coleman, a second-team All-SEC selection by league's coaches this season, recently completed his graduate degree. He started 12 of 13 games this season, missing the Idaho game with a right knee injury, started all 13 games during the 2014 season and appeared in 33 games during his Auburn career.

NFLDraftScout.com ranks Coleman as the No. 6 offensive tackle in the upcoming draft, likely to be selected in the first or second round.

The Memphis native confirmed he requested to be evaluated by the NFL's College Advisory Committee, which deems a player as a likely first-round pick, likely second-round pick, or neither.

Auburn coach Gus Malzahn would not say who submitted paperwork for an NFL evaluation and each team is limited to five such requests. Defensive end Carl Lawson announced his intentions to return for the 2016 season on Wednesday.

Coleman and right tackle Avery Young, who is considering his options for next season, were ranked among the top four tackles in the SEC this season by Pro Football Focus.

Coleman is over five years removed from being diagnosed with acute lymphoblastic leukemia. He beat the disease and recovered his strength before debuting for Auburn against Arkansas State in 2013.
