DENVER (AP) _ Dominik Hasek made 24 saves for his 43rd career shutout, and Miroslav Satan scored an unassisted, short-handed goal as the Buffalo Sabres beat Colorado 2-0 on Tuesday night.

Hasek, who returned to action a week ago after missing 40 games because of a groin injury, recorded only his second victory of the season. Colorado's Patrick Roy had 25 saves.

Dixon Ward added a goal with 3:58 left in the third period.

The victory snapped Buffalo's four-game road losing streak and ended Colorado's 12-game unbeaten streak at home.

The Avalanche played without star forward Peter Forsberg, who missed his second straight game because of a concussion.

In the opening period, Buffalo, which has the worst power play in the NHL, failed to capitalize on a four-minute high-sticking penalty against Colorado's Aaron Miller that included a 5-on-3 advantage for 45 seconds after an additional cross-checking penalty against Alexei Gusarov.

But at 13:41 of the period, Satan corralled a loose puck at mid-ice and scored from the slot _ his third short-handed goal of the season and 27th overall.

Colorado had an 8-2 advantage in shots in the second period, but again Hasek, protected by his teammates' neutral-zone pressure, was perfect in a scoreless period. Colorado had only three total shots on its three power plays in the period.

Ward made it 2-0, taking a pass from Satan in the right circle, crossing in front of the goal and backhanding a shot past Roy.
