REGINA — The Saskatchewan Roughriders acquired national safety Mike Edem from the B.C. Lions on Thursday.

The two teams also swapped conditional 2018 draft picks.

According to TSN's Farhan Lalji, Edem hasn't finalized a new deal with the Riders. If he doesn't restructure his contract Saskatchewan could still cut him.

The Lions would get a late round draft pick only if he plays at least one game with the Roughriders this season. 

The six-foot-one, 210-pound Edem was originally taken in the first round, third overall, in the 2013 CFL draft by the Montreal Alouettes. He was traded to the Hamilton Tiger-Cats in October 2015 before signing as a free agent with B.C. before last season.

Edem, 27, has started 33-of-60 career regular-season games, registering 91 tackles, 29 special-teams tackles, six interceptions and five sacks. He was a 2013 East Division all-star and Montreal's nominee as outstanding rookie.
