Buck Pierce is still waiting to find out whether a dislocated elbow will mean the end of his CFL season.

The injury-plagued Winnipeg Blue Bombers quarterback was wearing a brace on his right arm as he met with the media Wednesday. He suffered the injury to his throwing arm late in Sunday's loss to Saskatchewan.

"It's a pretty severe injury in the nature of the way that it happened, but this week we'll continue to evaluate it and go from there," said the six-year veteran.

Pierce, 28, added that doctors found a bone chip from the humerus and they're still doing tests to see if there is other damage.

The injury happened when Pierce fell and his elbow banged against a Saskatchewan player's helmet.

"It's very discouraging, but you have to take it for what it is and continue to stay positive and that's what I'm going to do," said Pierce, who'll be replaced by Steven Jyles. "It was a fluke thing and very unfortunate that it happened."

It's the second time this season Pierce has been injured, and fourth time over the past two years.

The injuries have been to four different areas of his body.

Pierce sprained his right knee earlier this season and missed a total of four games. He's started four games and only finished two with one win.

Last year with the B.C. Lions, he played 12 games. He suffered a concussion after the first seven games of the season, returned for five and then an injury to his non-throwing shoulder in October ended his season.

In his last 27 starts, he's left the game 10 times because of injury.

Pierce was released by the B.C. Lions in March and signed by Winnipeg the following month after the CFL team checked out his health and decided to take a chance on him.
