Gary Crowton was fired as the team's offensive co-ordinator and quarterbacks coach Sunday as the team continues to stumble on the field.
Marcel Bellefeuille will take over co-ordinator duties in Winnipeg (1-6) for the rest of the year. The Blue Bombers have lost five in a row, including a 37-18 loss to the Hamilton Tiger-Cats on Friday in Winnipeg.
"No one in our organization is happy with the way we have performed so far this season," said Bombers head coach Tim Burke. "Our offence has not played up to their standards and we need to make this change in order to give us a chance at remaining in the hunt for the post-season. I wish Gary all the best in his future endeavours."
Bellefeuille was added to Winnipeg's coaching staff on Aug. 12 after spending last season with the Omaha Nighthawks of the United Football League.
He was Hamilton's head coach from 2009-2011 and has an extensive background in the CFL, working as a position coach and offensive co-ordinator with the Saskatchewan Roughriders, Montreal Alouettes and Ticats.
Crowton isn't the first casualty of Winnipeg's rough start to the season.
Embattled CEO and president Garth Butchko resigned from his position and was replaced by former Blue Bomber player Wade Miller on Aug. 10.
Miller's first act as acting CEO was to fire general manager Joe Mack and name assistant general manager Kyle Walters as the acting general manager on Aug. 13.Suggest a correction
