REGINA -- Sadrick Williams was burned on the first play, but it was the last one that left his team scorched.
The Calgary Stampeders defensive back was flagged for offside during a successful onside kick by Sandro DeAngelis that Ryan Thelwell punched out of bounds.
Williams peeled off the backside and was 60 yards away from the play when the Stamps were flagged.
A second try was unsuccessful and the West semifinal was in the books.
He sat motionless in his locker long after the Stamps lost 26-24 to the Saskatchewan Roughriders.
"This is the worst thing to happen to me as a football player," said the second-year Stampeder. "This is a worst-case scenario. This is the worst thing that can happen for a football player and it happened to me."
Williams was meant to be just a distraction on the play, but ended up being the focus.
"I just came out going too fast," Williams said. "I was just trying to sell the play and I hurt my team."
On the first Roughriders offensive play, Williams was covering D.J. Flick, but the receiver gained some separation and was able to snag a Kerry Joseph pass.
Williams made a dive for a tackle, but missed, and could only watch as Flick ran in for a 56-yard touchdown.
After Williams went offside on the onside kick, the Stamps had another chance to get the ball, but DeAngelis' second boot was recovered by Riders receiver Khalil Hill.
Stamps head coach Tom Higgins hopes Williams doesn't blame himself for the loss.
"It might scar the young man for a while," Higgins said. "I hope he gets over it and realizes no one is perfect.
"It's going to haunt the young man for a long time. He can get over it as we all can get over it."
