The Winnipeg Blue Bombers, who are struggling at the quarterback position, have discussed the idea of signing free agent Michael Bishop, Sportsnet.ca has learned.

A source said the Bombers' football operations staff has mentioned Bishop's name.

"I don't know how serious they are," the source said.

The Bombers have been getting little production out of the quarterback position this season and hit rock bottom using all three pivots - Stefan LeFors, who was acquired in the off-season to Edmonton to become the starter but has faltered badly, Bryan Randall and Richie Williams - in a 19-5 loss to the Toronto Argonauts on Friday.

Bishop has been out of football since the Saskatchewan Roughriders cut him after last season.

The Roughriders acquired the strong-armed pivot from the Argos midway through last season, surrendering a conditional draft pick. Bishop started eight games for the Riders, but was released two days after a disappointing game in Saskatchewan's 33-12 Western Semi-Final loss to the B.C. Lions.

He has been working out in Texas in hopes of resurrecting his career.

Bishop began his Canadian Football League career with the Argos in 2002 and had an 11-1 record as a starter in 2007, but lost his starting role in 2008 when the team acquired Kerry Joseph in the off-season from Saskatchewan.
