The Detroit Lions already have a one-two punch in the backfield, but the team could add another running back into the mix. According to the NFL Network's Ian Rapoport, the Lions are working out former Seattle Seahawks running back, CJ Prosise.

In the 2020 NFL Draft, Detroit added D'Andre Swift in the second round (35th overall pick). Seeing that they used an early-round pick on Swift, the rookie rusher figures to have a chance to be the featured back in the offense.

Of course, besides Swift, Kerryon Johnson is also expected to see a decent-sized role in the backfield. Similar to Swift, Johnson was the Lions' second-round selection in the 2018 NFL Draft. Sadly, injuries have prevented Johnson from being able to prove he can be a franchise running back in the NFL.

As for Prosise, he's spent his first four seasons in the NFL with the Seahawks. Back in 2016, Prosise was drafted by Seattle in the third round out of Notre Dame. After converting from wide receiver to running back in college, Prosise has excelled as a receiving back.

Despite his seldom usage in Seattle, Prosise has hauled in 36 passes for 393 yards since 2016. At the same time, he's rushed for 264 yards on 65 attempts and he's found the end zone twice.

Besides Swift and Johnson, the Lions also have Bo Scarbrough and Ty Johnson at running back. Both Scarbrough and Johnson were given chances to start last season due to injuries in Detroit's backfield. Nevertheless, the Lions could be looking to add a veteran presence to the backfield in Prosise.
