CALGARY - Calgary coach John Hufnagel says star running back Jon Cornish is unlikely to play when the Stampeders host the Saskatchewan Roughriders on Friday.

In a post on the Stampeders' official Twitter account, Hufnagel says Cornish will likely miss the game "due to general soreness."

The Stampeders (13-2) have already clinched first place in the West Division and will want to have a healthy Cornish in the post-season.

Cornish, from New Westminster, B.C., leads the league in rushing with 977 yards despite missing seven games this season to injury.

Cornish missed six contests in July and August with concussion-like symptoms and didn't play against Montreal in September with what the tam called "nagging injuries."

In other roster news, veteran receiver Chris Bauman was added to the practice roster and was on the field while defensive lineman Quinton Spears was released.

This is the second stint with the Stampeders for Bauman, who spent two seasons with Calgary after playing four seasons with the Hamilton Tiger-Cats and one with the Edmonton Eskimos.
