Williams had a breakout season in 2010, starting in all 16 games and leading the team with a career-high six interceptions and a career-best 23 passes defensed.
In 2010, Clabo was part of a Falcons offensive line that averaged 341.1 yards of total offense per game and allowed just 23 sacks, the third-fewest in the NFL.
Clabo will replace Philadelphia Eagles offensive tackle Jason Peters and join defensive end John Abraham, tight end Tony Gonzalez, fullback Ovie Mughelli, quarterback Matt Ryan, running back Michael Turner, wide receiver/special teamer Eric Weems and wide receiver Roddy White as Falcons in Hawaii for the Jan. 30 game. The Falcons have a league-high and franchise-record eight players on the NFC roster.
