As an undrafted rookie in 2018, Olasunkanmi Adeniyi was one of the bright young lights for the Pittsburgh Steelers in the offseason. He picked up three sacks in the preseason, two of them producing fumbles, as he picked up steam to make a run at a roster spot.
While he did make the team, his momentum came to a grinding halt with a hamstring injury suffered in the final preseason game. After he was kept on the initial 53-man roster, they quickly shifted him to the Reserve/Injured List, waiting for the cut-downs so that they could move him while retaining his eligibility to be Designated for Return.
