Zach Collaros is going to be unveiled to the province of Saskatchewan on Tuesday, according to Rod Pedersen.
Collaros was acquired by Saskatchewan in a trade with Hamilton that sent a Riders second-round draft pick to the Ticats.
The 29-year-old has played 59 career CFL games with the Argos (2012-13) and Ticats (2014-17), accumulating 1,127 pass completions on 1,694 attempts (66.5%) for 13,759 yards, 83 touchdowns and 38 interceptions. He brings a 24-27 record to Regina.
Collaros will put on green and white for the first time.
