The Lions let quarterback Alex Ross and defensive lineman DeQuin Evans go while adding another pivot.
Ross was a CFL rookie in 2017 and played in four games completing 5-of-12 passes for 82 yards and two interceptions.
Evans signed as a free agent in B.C. last off-season and suited up in five games making eight tackles, one sack and one forced fumble. Over 23 CFL games with the Lions, Alouettes and Stampeders, Evans has 31 tackles, five sacks and one forced fumble.
Meanwhile, the Lions inked quarterback Ricky Lloyd who played 33 games at Minnesota State during his university career, throwing for 3,379 yards and 36 touchdowns for the Mavericks.
