Calgary Stampeders quarterback Bo Levi Mitchell worked out for the Denver Broncos on Tuesday, per NFL sources.

It was the second of five NFL workouts Mitchell had scheduled going into December after the Minnesota Vikings flew the reigning CFL most outstanding player in for an up-close look last week.

Mitchell capped yet another stellar season in 2018 by leading the Calgary Stampeders to a CFL championship. The 28-year-old became the first player in league history to throw for more than 5,000 yards without having a single receiver record 1,000 yards. Despite an ever-changing receiving core, Mitchell adapted on the fly and still led the CFL in touchdown passes with 35.

Mitchell has two Grey Cups, two CFL title game MVP awards and two CFL MOP trophies on his resume. Exactly the type of year NFL talent evaluators wanted to see from Mitchell.

“Accurate, poised and makes plays. He has all the accolades you could ask for in the CFL,” one NFL scout said.

The prolific CFL quarterback is generating legitimate NFL buzz.
