Dangerfield, 27, originally signed on with the Bills as an undrafted free agent out of Towson back in 2013. He lasted just a few months in Buffalo before he was cut at the start of the 2013 season.
The Steelers later signed him to a future/reserve contract after the season and he was on and off of their practice squad the past few years before making the 53-man roster last season.
Pittsburgh signed him to a one-year, $540,000 deal back in January, but decided to waive him with an injury designation and eventually cut him from their injured reserve with a settlement.
In 2016, Dangerfield appeared in 14 games for the Steelers and recorded 16 tackles and no interceptions.
