Bass, 26, was a seventh-round pick of the Oakland Raiders in 2013, though he spent his first two seasons in Chicago after being cut by the Raiders before the start of his rookie season. In four seasons with the Bears and Tennessee Titans, the 6-foot-4, 263-pound Bass has appeared in 49 games, starting nine. He has 5.5 career sacks, including a career-best 3.0 in 2014, as well as 85 total tackles, five passes defensed and two interceptions, one of which he returned for a touchdown as a rookie.
