The Saskatchewan Roughriders have released quarterback Kevin Glenn. 

The release was announced Thursday morning, a day after the Riders acquired QB Zach Collaros from the Hamilton Tiger-Cats.

Glenn was signed by the Riders last January after the departure of long-time pivot Darian Durant. It was Glenn's third stint with the green and white.

Glenn, 38, played 17 games last season, throwing for 4,038 yards and 25 touchdowns.

Collaros, 29, was acquired for a second-round, 10th overall draft choice by the Riders, who posted a 10-8 record in 2017.

The 2018 draft pick was acquired by the Riders when they traded Durant to the Montreal Alouettes.
