CLEMSON, S.C. — Suspended Clemson defensive tackle Dexter Lawrence is headed to the NFL.

Lawrence is the 350-pound, 6-foot-4 lineman who missed the Tigers’ College Football Playoff games after he and two teammates tested positive for the banned substance ostarine. Lawrence attended both games and celebrated with teammates Monday night after a 44-16 victory over Alabama in the national championship game.

Lawrence announced his decision on Twitter Wednesday.

He was a three-year starter and is considered a first-round NFL pick in next spring’s draft.

He is the third Clemson starter on defense to give up his eligibility to go pro. Earlier, cornerback Trayvon Mullen and linebacker Tre Lamar said they would enter the NFL draft. Mullen was the defensive MVP of the championship game.
