I don't think so. They were here at different times.
I believe Doug was 1990-1991 and Darren was 1992-1995 but I could be wrong. If I'm wrong,it wouldn't be the first time.
Yes , the Flutie brothers did play for the Lions at the same time . Doug was the one who got the Lions to bring his brother on board . BC was the only they both played together on as pros. Can't recall if it was for just one season or two . Then Doug left to play for the Stamps while Darren stayed here until he moved on also , but not before winning the Grey Cup first after his team had knocked brother Dougs Stamps out of the '94 West Final.
