Report: No time frame for Stamps’ Mitchell

CALGARY — The Calgary Stampeders have not yet determined a time frame for injured quarterback Bo Levi Mitchell, TSN’s Farhan Lalji reported Wednesday.

The veteran quarterback suffered an upper body injury in Week 3 and underwent an MRI on Tuesday, but the team is reportedly seeking a second opinion on the results.

Mitchell left the game with what initially looked like shoulder discomfort late in a 36-32 win over the BC Lions on Saturday. However, he said after the game in an interview that his shoulder wasn’t affected, instead indicating it was his pectoral muscle.

» Stamps pull off incredible comeback win over Lions

Nick Arbuckle is expected to get the start on Saturday when the Stampeders take on the Saskatchewan Roughriders at Mosaic Stadium. Arbuckle, a 25-year-old sophomore, was spectacular in relief last weekend, completing all nine attempts and finding the end zone twice to lead an impressive last-game comeback.

Despite a slow start this season — averaging just 7.2 yards per attempt with three touchdowns and two interceptions — Mitchell is considered one of the best quarterbacks in the CFL. The two-time Grey Cup Champion and Most Outstanding Player signed a four-year contract extension in the off-season.
