Henderson came to the Green & White last year after sitting out the 2014 season following six seasons, the last three as a starter, with Minnesota.
He played in all 16 games in '15 and logged 455 total plays in his return to the NFL, with most coming in the final six games (40 defensive tackles, 5.5 tackles for loss/no gain) as he rotated in at inside LB with Demario Davis. He racked up 14 tackles in the season finale at Buffalo, equaling a career high.
Henderson also contributed on special teams with 12 coverage tackles, second-most on the team behind Trevor Reilly's 16, and forced a fumble on a punt return in the fourth quarter of the loss at Houston.
