Mitchell, 26, wound up going undrafted out of Northwestern State back in 2016. He later signed on with the CFL’s Edmonton Eskimos and spent three years in Canada.
The Cardinals signed Mitchell to a futures contract this past January. However, Arizona cut him loose back in May and he later caught on with the Buccaneers.
For his career, Mitchell has caught 97 passes for 1,418 yards receiving and six touchdowns over the course of 19 games.
