Canadian safety Marc-Olivier Brouillette has retired, per sources.

The Saskatchewan Roughriders signed Brouillette as free agent in February, hoping he could serve as a starter at safety and give the team some much-needed ratio flexibility.

Drafted 23rd overall by Montreal in the 2010 CFL Draft, the 31-year-old Brouillette has played in 102 games and made 64 starts in his seven seasons with the Alouettes. He started all 18 games last season making 33 defensive tackles, three special teams tackles and registering one interception while being named an East all-star.

Brouillette has a law degree and sources say he’s now going to pursue a legal career. He also has a history of concussions and once said he’d retire if he suffered another one.

The Montreal Carabins product received a signing bonus when he inked his deal with the Riders but sources say he is intending to return the money to the team.

The timing could certainly be better as the Riders are set to open training camp on Sunday in Saskatoon.
