Watson played with a torn ligament in the Tigers' 35-17 victory over South Carolina in November and had surgery on his right knee in December. Swinney has said Watson has had above average rehabilitation and has looked strong the past several weeks.
Swinney said Wednesday his sophomore passer was given the green light to go full out once Clemson opens practice next month.
Watson played in eight games and made five starts last season, throwing for 1,466 yards and 14 touchdowns. He missed three games after injuring his right, throwing hand against Louisville. Watson missed two more contests after hurting the knee at Georgia Tech.
