CLEMSON - Former Clemson offensive tackle Brandon Thomas absorbed a major blow to his 2014 NFL draft stock, tearing the ACL in his right knee during training last week.

Thomas' agent, Tom Kleine, said Monday that Thomas had already completed "seven or eight" individual workouts with separate NFL teams and had several more scheduled.

"As you can imagine, he's kind of running the gamut of emotions. Training was going great," Kleine said when reached by phone Monday. "We're just still in the process of notifying teams. Will it affect his stock? Probably."

After strong performances at the NFL Scouting Combine and at Clemson's Pro Day, Thomas had been regarded as a solid second-round prospect by numerous publications with a potential move to the interior line.

"He was a left tackle who played well (in college) and did a good job at the Senior Bowl practices," ESPN draft analyst Mel Kiper Jr. said Feb. 6. "He could play as guard, and be a great guard, a Pro Bowl guard."

The 6-3, 317-pound Thomas was a first-team All-Atlantic Coast Conference left tackle his last two years in college. He trained for the combine in Atlanta but recently has been working out in Clemson.
