It may be a while before we see Ryan White back in the Canadiens' lineup.

White emerged from purgatory Thursday, but his night turned into a hockey hell as he took a double minor penalty that allowed the Buffalo Sabres to launch a comeback that ended in a 5-4 shootout victory.

"It was unacceptable," said head coach Michel Therrien. "That's the third time he has cost us with undisciplined play."

The last time was last Wednesday in Ottawa when White, whose game is based on being a physical player, took a roughing penalty and then received another two minutes for mouthing off to the referee. The Senators scored twice with White in the box to snap a 1-1 tie and went to a 5-1 win.

White watched the next three games from the penalty box, but an injury to Travis Moen offered him a chance at redemption.

He blew it.

This time around, White took a two-minute roughing penalty and then received another two when he failed to goad Steve Ott into a fight. A 4-2 lead was cut to one goal when Thomas Vanek scored 25 seconds later.

"Obviously, it was a selfish play," White said. "I thought he went kind of low on me and that's what he does. He's a smart player and I reacted in the wrong way. I cost my teammates another two points."
