The Atlanta Falcons on Thursday agreed to terms with one of their own free agents, defensive end Adrian Clayborn.
The Falcons signed Clayborn during the 2015 offseason, and in his first season in Atlanta, Clayborn played in all 16 games. He also recorded 15 total tackles (14 solo), three sacks, and one fumble recovery.
Veteran defense end Chris Long is visiting the Falcons Thursday as the Atlanta clearly looks to upgrade its defensive front four and pass rush.
Long, who was the overall No. 2 pick in the 2008 NFL Draft has 54.5 career sacks but has been limited to 18 games the past two seasons.
Clayborn originally was selected by the Tampa Bay Buccaneers in the first round with the 20th pick in the 2011 NFL Draft. The former Iowa Hawkeyes standout had started all 36 games during his four years with the Bucs.
He compiled 109 total tackles (74 solo), 13 sacks, five forced fumbles and two passes defensed.
The signing of Clayborn followed a flurry of moves on Wednesday.
The Falcons and former Cleveland center Alex Mack agreed to a five-year deal that will become official pending a physical. Mack will reportedly receive full guarantees on the first two seasons of the deal and more than recoup $24 million left on the table with the Browns.
The Falcons also signed former Miami Dolphins defensive end Derrick Shelby and agreed to terms with quarterback Matt Schaub, who returns to the franchise that selected him in the third round of the 2004 NFL Draft.
Nose tackle Paul Soliai was released.
