Coming off their first road win in a month, the Chicago Blackhawks could be without Martin Havlat when they return home to face the Edmonton Oilers on Sunday night.
Chicago (17-15-2) rallied from two goals down to win 4-3 in overtime at Ottawa on Saturday for its second straight victory and its first away from home since beating Calgary on Nov. 22. It was just the third win in nine December games for the Blackhawks, who play their final three games of 2007 at home.
"You have to come to play every night and I think it showed," Chicago's Patrick Sharp said. "It's a good confidence-booster for our team and hopefully we can build off of it."
The Blackhawks, though, might be without Havlat after he suffered a groin injury during his first game in Ottawa since he was traded by the Senators to Chicago in July 2006.
"We'll see how he is (Sunday)," Chicago coach Denis Savard said.
Havlat missed 22 games after injuring his shoulder in the season opener. He sat out 26 last season due to ankle, shoulder and groin injuries.
Chicago, though, was able to get by without Havlat - who has five goals and six assists in 12 games - earlier this season as it went 12-8-2 without him.
Rookie Jonathan Toews scored the game winner and added two assists. Sharp had a goal and set up Toews for the Blackhawks, who have nine goals in their last two games after scoring just two while losing their previous two contests.
Sharp has three goals in his last two games and scored in Chicago's 2-1 win over Edmonton on April 1 in the teams' most recent meeting at the United Center. He did not play in the Blackhawks' 3-2 shootout loss at Edmonton on Nov. 24 because of flu-like symptoms.
Chicago will be looking for its third straight home win over Edmonton, and is 3-0-2 versus the Oilers there since its last regulation loss in the series in January 2004.
Edmonton (16-17-3) lost 3-1 at home to New Jersey on Friday as it failed to earn at least one point in its last six games.
The Oilers, who have won their last two road games and four of their last five away from home, couldn't hold a 1-0 lead after two periods against the Devils.
"We just gave that game away," said Oilers coach Craig MacTavish, whose team had two shots on goal in the second period. "It was Christmas time and we wrapped it up and gave it to them."
Joni Pitkanen scored the lone goal for the Oilers, who have been outscored 5-1 in their last two contests. Ales Hemsky recorded his team-leading 19th assist Friday night.
Hemsky, who has 10 points in his last nine games, had a goal against Chicago last month.
Mathieu Garon made 30 saves Friday and could make his second straight start as Dwayne Roloson continues to suffer from strep throat. Garon is 4-1-0 with a 1.93 goals-against average against the Blackhawks.
