Desperate for stability at the quarterback position, the Winnipeg Blue Bombers confirmed Sunday that Michael Bishop will be brought to practice ahead of their Week 5 battle with the Toronto Argonauts.

Team officials confirmed Bishop's arrival, with a contract for the veteran not yet officially registered with the 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.

The nadir was reached in a 19-5 loss to Toronto on Friday, when Stefan LeFors, Bryan Randall and Richie Williams combined for 11-of-26 completions for just 66 yards — and two interceptions.

Bishop, 33, was the longtime backup for Toronto until he threw 22 touchdowns and 11 interceptions in 2007 as a starter.

But the Argonauts acquired Kerry Joseph before the 2008 season, and the pair coexisted uneasily. Bishop was traded to Saskatchewan midway through the season.

Bishop threw for seven touchdowns and completed nearly 61 per cent of his passes with the Roughriders — nearly 10 percentage points higher than his usual standard — but he also racked up 12 interceptions.

Saskatchewan parted ways with Bishop, who most recently played with the Corpus Christi Hammerheads in the Indoor Football League.

For his CFL career, Bishop has thrown for 51 touchdowns and 8,737 yards, with 56 interceptions. He has also racked up 1,303 yards and 12 touchdowns running the football.

The quarterback situation has put pressure on first-year coach Winnipeg Mike Kelly, who handpicked LeFors in the off-season by acquiring him from Edmonton.

The Bombers in the offseason released longtime starter Kevin Glenn, as well as Ryan Dinwiddie, the injury replacement for Glenn in the team's 2007 Grey Cup loss.
