Saskatchewan Roughriders quarterback Zach Collaros took part practice on Monday.

The Riders had a light workout while preparing to host the Winnipeg Blue Bombers in the West Semifinal on Sunday. Collaros went through the session taking all the reps as a starting quarterback normally would do.

Collaros was knocked out of the Riders last game in Week 20 when B.C. Lions defensive lineman Odell Willis delivered a controversial hit on the 30-year-old. Saskatchewan’s pivot stayed in the game despite being in visible discomfort.

During 14 games in the regular season, Collaros completed 61 per cent of his passes (234-of-382) for 2,999 yards, nine touchdowns against 13 interceptions.

While the Riders were on a bye for the final week of the regular season, the Riders signed veteran quarterback Drew Tate, prompting some concern about Collaros’ health status. But all signs point to Collaros starting in the first playoff game at new Mosaic Stadium.
