Cole, 26, left Week 9’s game with a fractured ankle and there had been talk that his season was likely over, so this shouldn’t come as a big surprise.
He’s in the final year of his contract and stands to make a base salary of $660,000 for the 2015 season before testing the open market next year.
Cole’s 2015 season ends with him recording three tackles and a fumble recovery over the course of seven games.
Trusnik, 31, originally signed on with the Jets as an undrafted free agent out of back in 2007. He was later traded to the Browns before later signing with the Dolphins in 2011.
The Panthers signed him to a one-year deal back in March, but he was unfortunately among their final roster cuts.
In 2014, Trusnik appeared in all 16 games for the Dolphins and recorded 50 tackles, an interception, two fumble recoveries and two pass defenses. Pro Football Focus has him down for playing 397 total snaps last year to go along with a solid rating as a run-defender.
