Calgary Stampeders quarterback Bo Levi Mitchell was impressive in his workout with the Minnesota Vikings on Wednesday, sources told TSN's Davis Sanchez.

Mitchell worked out in front of more than 20 Vikings coaches and staff including head coach Mike Zimmer. The Vikings came away impressed with Mitchell's velocity, according to Sanchez, and believe that the 2018 CFL Most Outstanding Player is capable of making all the throws playing at the NFL level requires.

During the workout, Mitchell threw exclusively to Ottawa Redblacks receiver Diontae Spencer, who was also working out for the team. Spencer, who also returned kicks for the Redblacks, was impressive in return drills, according to Sanchez. Spencer was named a CFL All-Star on special teams Tuesday.

Redblacks linebacker Chris Ackie also worked out for the Vikings on Wednesday and impressed the evaluators on hand, according to Sanchez.

Today's workout, which was the first known NFL workout for Mitchell since leading the Stampeders to a win in the 2018 Grey Cup and being named the game's MVP, was a quick one. The Vikings only had Mitchell throw 15 passes, per Sanchez, with the team more or less looking to verify what they've already taken away from watching his game footage. He has several other workouts with other teams lined up in the coming weeks, per Sanchez.

In addition to today's workouts, both Spencer and Ackie have drawn NFL interest in previous years.
