The Tampa Bay Buccaneers have reached an agreement with their first-round draft pick Adrian Clayborn, according to ESPN's Adam Schefter. The Bucs defensive end was eager to get to work as he was already in the building on Tuesday getting acquainted with his new teammates and coaches. Under the new CBA, Clayborn's contract will be a four-year deal with a fifth-year option held by the team. His deal is worth a total of $8.2 million over four years and is fully guaranteed.

Clayborn is the first player of this year's first-round draft class to be signed and also the first ever first-round pick signed under the new CBA. The Iowa product is the third member of Tampa Bay's draft class to sign their rookie contract after third-round draft selection LB Mason Foster and seventh-round draft pick TE Daniel Hardy both agree to four-year deals on Tuesday afternoon.

The Bucs selected Clayborn with the 20th overall pick in the first round of the 2011 NFL Draft. Tampa Bay decided to pair Clayborn with another high-profile defensive end as the team selected Clemson's Da'Quan Bowers in the second round.

The 6-foot-3, 281-pound Clayborn is expected to contribute right away for the Bucs and will have the chance to be the team's starting right end on opening day against the Detroit Lions. Clayborn, 23, is a power football player that uses his strength to rip off blocks and shed offensive linemen to the side in order to open up a lane to get to the quarterback. Clayborn also excels at bull rushing tackles. The former Hawkeye is expected to boost the Bucs run defense as he is stout at the point of attack and plays with very good leverage due to his stature and strength.

Clayborn broke out in 2010 as a junior when he totaled 70 tackles with 11.5 sacks, 20 tackles for a loss, and four forced fumbles. He also blocked a punt and returned it 53 yards for a touchdown against Penn State. During his senior campaign, Clayborn made 52 tackles with 3.5 sacks, 7 tackles for a loss, one forced fumble, and one blocked kick. Throughout his collegiate career, Clayborn totaled 192 tackles with 37.5 tackles for a loss, 19 sacks, seven forced fumbles, eight passes patted down, and three blocked kicks. The former Iowa standout was a team captain in college and brings that same fire and energy to a young Tampa Bay football team.
