CALGARY - The Calgary Stampeders' season has gone from bad to worse.
Head coach Dave Dickenson said Tuesday the club is placing veteran quarterback Bo Levi Mitchell on the six-game injured list with a broken fibula.
Mitchell, twice the CFL's outstanding player, was hurt in Calgary's season-opening 23-20 home loss to the Toronto Argonauts on Aug. 7.
The 31-year-old Texan played in Calgary's 15-9 loss to the B.C. Lions on Thursday, throwing four interceptions.
This season, Mitchell has completed 44-of-73 passes for 542 yards with a TD and five interceptions.
The expectation is Ottawa's Michael O'Connor will start for Calgary (0-2) when it hosts the Montreal Alouettes (1-0) on Friday night.
