The Winnipeg Blue Bombers placed veteran quarterback Michael Bishop on their practice roster Monday.
Bishop, 33, arrived in Winnipeg late Sunday, just two days after the team's dreadful offensive showing in a 19-5 home loss to Toronto.
Bishop has thrown for 51 touchdowns and 8,737 yards in a CFL career spent with Toronto and Saskatchewan, to go along with 56 interceptions. He has also racked up 1,303 yards and 12 touchdowns running the football.
Since the Riders parted ways with him after last season, Bishop was toiling for the Corpus Christi Hammerheads in the Indoor Football League.
Winnipeg (1-3) has scored the fewest points in the CFL this season after failing to get an offensive touchdown in its last two games.
Starter Stefan LeFors, Bryan Randall and Richie Williams combined for just 66 yards passing in the loss to the Argonauts. LeFors and Randall threw interceptions.
First-year Winnipeg coach Mike Kelly handpicked LeFors in the off-season by acquiring him from Edmonton.
The Bombers released longtime starter Kevin Glenn, as well as Ryan Dinwiddie, the injury replacement for Glenn in the team's 2007 Grey Cup loss.
The Bombers and Argos will meet again Saturday in Toronto.
