Johnson, 28, wound up signing on with the Broncos back in 2012. He spent three years in Denver before he was among their final roster cuts at the start of the 2015 season.
The Titans elected to claim him off of waivers and he finished out the year in Tennessee. Johnson signed a one-year, $840,000 contract with the Steelers back in March.
In 2016, Johnson has appeared in six games and recorded six tackles and a forced fumble for the Steelers.
Fort, 26, originally signed on with the Browns as an undrafted free agent out of Northern Iowa back in 2012. He last just over a year in Cleveland before he was among their final roster cuts.
Since then, Fort has played for the Broncos and Seahawks before signing a future/reserve contract with the Bengals. Unfortunately, the Bengals waived him right before the 2015 NFL Draft.
The Patriots later signed him to a contract, but he was later waived and claimed by the Steelers. Pittsburgh cut Fort loose at the start of the season before signing him to their practice squad a day later.
The Steelers decided to promote Fort to their active roster back in December of last year. Pittsburgh cut him loose this past weekend.
In 2016, Fort has appeared in seven games for the Steelers and recorded four total tackles during that time.
