Source: Da'Quan Bowers will just lift

Clemson defensive end Da'Quan Bowers, ranked as the top available prospect in Scouts Inc.'s top 32 and projected as a top-five pick in April's draft, plans only to lift at this week's NFL scouting combine, a league source told ESPN NFL Insider Adam Schefter.

The combine is scheduled to begin Wednesday and will end March 1.

The 6-foot-4, 280-pound junior had 67 tackles last season and led the nation with 16 sacks. He announced last month that he was giving up his final season of eligibility to declare for the NFL draft.

Bowers won the Bronko Nagurski Trophy as the nation's top defensive player, bursting onto the scene after compiling just four sacks in his first two college seasons.

Bowers, one of the most highly recruited players in his high school class, had a breakout season after the deaths of his father, Dennis, and close friend and mentor Gaines Adams of the Chicago Bears.

Bowers had shed 15 pounds and was performing well in preseason camp in August when his father collapsed while performing in his gospel band. Bowers later was visiting him in the hospital when his father suffered a seizure and died. Bowers spent two weeks away before rejoining the team.

Bowers, wearing Adams' old No. 93, had a sack in nine straight games last season, breaking Adams' record by a game. He also surpassed Adams' record for sacks by a defensive lineman.
