TORONTO — According to TSN’s Matthew Scianitti, injured Toronto Argonauts running back Anthony Coombs will undergo shoulder surgery.

Argos head coach Marc Trestman added that he’s hopeful Coombs can return before the end of the season.

A former first round pick now in his fourth CFL season, Coombs was enjoying a career year with the Argos, hauling in 47 passes for 426 yards and a touchdown in nine games.

Three of those receptions came during Saturday’s 38-6 win over the Montreal Alouettes before the 24-year-old sustained the injury and was forced to leave the game.

While Coombs’ injury is a setback for the Argos’ offence, they could be close to getting a key defensive cog back on the field. Trestman added Monday that CFL sack leader Victor Butler is working out after being sidelined since Week 5 — although he remains day to day.

Cleyon Laing and Akwasi Owusu-Ansah are also considered day to day with knee injuries.

The Argos, who lead the CFL East Division with a 4-5 record, are back in action on Saturday night when they visit Calgary’s McMahon Stadium.
