Veteran fullback Charlie Power has suffered a suspected torn Achilles tendon, according to Calgary play-by-play radio announcer Mark Stephen.
Power was a fourth-round pick out of the University of Saskatchewan in 2013 and has been a member of the Stampeders ever since, appearing in 85 regular season games.
The six-foot-three, 245-pounder is predominantly a blocker on offence, though he has also made seven receptions for 37 yards. He really shines on special teams, having recorded 69 special teams tackles and three forced fumbles over the course of his career.
The two-time Grey Cup champion will be replaced by Calvin McCarty, who came out of retirement to sign with the team on Sunday.
The Stampeders open the 2021 season at home to the Toronto Argonauts on Saturday, Aug. 7.
