The Edmonton Eskimos, coming off a humiliating 52-5 Labour Day loss to the Calgary Stampeders, continue to shake up their roster.
The CFL team announced it has signed former NFL wide receiver Marko Mitchell and cut starting offensive tackle Calvin Armstrong.
Mitchell played 10 games for the Washington Redskins in his rookie year last season, catching four passes for 32 yards.
The 25-year-old, eventually waived by Washington, was released last week by the Minnesota Vikings.
Armstrong, 28, had started almost every game for the Eskimos since signing with the club as a free agent prior to the 2008 season.
The team has also released receivers Tremayne Kirkland and Kevin Wuthrich.
