The Saskatchewan Roughriders have signed four players, three of whom finished the season on the practice roster with other teams.
Quarterback Bryan Bennett has spent more than a year with Winnipeg while receiver Thomas Mayo played in five games with the Bombers in 2016. Offensive lineman Terrence Campbell started six games with the Hamilton Tiger-Cats at right tackle before moving to the PR.
Linebacker Kenny Horsley spent the final two weeks of the season on the Riders practice roster.
Players who finish the season on the practice roster are automatically released at the end of the season and become free agents.
