BOSTON — Needless to say, Buffalo head coach Lindy Ruff was disappointed with his team’s 3-2 overtime loss tonight in Game 4 of the Eastern Conference quarterfinal series with the Bruins.

But he was a lot more critical of the officiating than his team’s play after the game.

The Bruins started their comeback from 2-0 down in the third after Cody McCormick was whistled for goaltender interference 1:58 into the stanza. David Krejci scored just nine seconds later.

The Bruins didn’t capitalize on a Patrick Kaleta boarding call at 2:34, but built the momentum that led to their tying goal off Patrice Bergeron’s stick at 6:40 of the period.

“The call on McCormick wasn’t a call. Their own guy took their goaltender out,” Ruff said. “And if Pat Kaleta hitting [Milan] Lucic is a call … that’s strange. I thought we were getting a power play on the McCormick play .. their own guy took the goaltender out. Pretty big swing in momentum for us.”

Ruff was later asked if the Sabres “blew their chance” to even up the series. He again pointed the blame at the officials.

“We didn’t blow it,” he said. “I just explained what happened. We didn’t blow it. Nobody blew it. Do you think Pat Kaleta hitting Lucic was a penalty? And [Mark] Recchi hitting [Tim] Kennedy is a penalty .. is it not? Is that the same? Case closed.”

The case is close, and the verdict is a 3-1 Bruins lead in the series with Game 5 Friday.
