A quarterback's effectiveness begins and ends with the thumb on his throwing hand.
If it's not 100% healthy, well, there's not much point in playing.
And that means Winnipeg Blue Bombers No. 1 quarterback Kevin Glenn, who has an injured right thumb, could be in danger of missing his fourth start in eight games this Saturday night.
The Bombers will host the winless Hamilton Tiger-Cats (0-6) Saturday at Canad Inns Stadium in a game they desperately need to win.
"With something like this, you want to be able to function right," Glenn said yesterday. "I don't want to be out there and one out of every two passes is not right.
"It starts with your hand, so if you're not able to throw the ball or hold the ball, you can't do anything."
Glenn got hurt in the first quarter of Saturday's 30-21 loss to the Calgary Stampeders at McMahon Stadium. Just as he was delivering a pass, he smacked his thumb on the helmet of hard-charging Stamps linebacker John Grace.
Glenn left the game because he couldn't grip the ball. The area at the base of his thumb was still swollen yesterday afternoon, and he was expected to have it X-rayed last night.
The preliminary diagnosis was either a jammed thumb, a minor sprain or a bruised bone. There doesn't appear to be any ligament damage, which Glenn said is a good sign.
Bombers offensive co-ordinator Mike Gibson said the team will be patient with Glenn's injury this week, and it won't declare Tee Martin, Russ Michna or even Spergon Wynn the starter when practice resumes tomorrow.
"It's too early to say that," Gibson said. "First of all, we gotta find out how Kevin is, and then we'll go from there."
MASTER SPEAKER: Gibson has been coaching football for 26 years, so he knew how to answer a question yesterday about the officiating during Saturday night's game.
"They say in a season (calls) all even out? Well, we're probably gonna have some good calls coming our way," Gibson said.
LATE HITS: Aside from Glenn, it's believed the Bombers suffered no other significant injuries during Saturday's game ... There's a chance that Hamilton QB Danny McManus could be back for Saturday's game against the Bombers. He missed the Ticats' game over the weekend with an injured thumb.
