The mystery surrounding Ryan Kesler's second-period exit to the Vancouver Canucks dressing room on Tuesday night has finally been solved.

So what was it, Ryan? Pulled groin? Bad ankle? Bum knee?

"I just had to go call my wife," Kesler said Thursday. "I thought I'd left the iron on."

See, that's why B.C. Hydro hired him to do those Power Smart commercials.

Of course, Kesler, nor anyone else in the Canuck organization, is saying what exactly the problem was when he limped to the dressing room favouring his left leg.

All Kesler would say Thursday was that he feels fine and he knew Tuesday night that he'd be back. Not only did he return, but he scored the tying goal that forced overtime in Game 5 of the Western Conference final.

"There wasn't a time where I thought I wasn't going to come back out," Kesler said.

His teammates had an inkling he'd be back, too.

"I think his determination was pretty evident," said defenceman Kevin Bieksa, who won the game in double overtime. "I don't think anyone expected him to stay in the room for long. I was in the penalty box when I saw him go the dressing room so I didn't know what happened. I wasn't too worried. I knew Kes would come back. He always does.

"That's what kind of guy he is. He's very determined and won't let anything stop him. I'm sure if it had been anything serious they would have just cut it off and put a prosthetic on and he would have kept playing and probably still scored that goal."

Coach Alain Vigneault didn't quite know what to think when he saw Kesler pull up while trying to check San Jose defenceman Dan Boyle in the neutral zone.

"I wasn't quite sure what happened," Vigneault said. "I saw him skate and then all of a sudden stop skating. Bernie (trainer Mike Burnstein) came to me a minute or two after and said, 'don't worry he'll be right back.' I'm not sure what happened in there, but what Bernie told me was that he'd come right back and he did and he played real hard."
