CHICAGO -- Just when it appeared Marian Hossa's 500th career goal appeared to give them more than enough breathing room, the Chicago Blackhawks found themselves fighting just to hang on.

As it turned out, the Blackhawks had a little something left when it mattered most.

Artemi Panarin and Artem Anisimov each scored twice and added late goals as the Blackhawks rallied to beat the Philadelphia Flyers 7-4 on Tuesday night at the United Center.

Panarin's second goal came with less than four minutes to play after Anisimov snapped a 4-4 tie with a wrist shot at the 10:24 mark of the third period. Anisimov added an empty-netter to cap the scoring.

The three goals came after the Blackhawks (2-2) had allowed four straight goals.

"The games go both ways," Anisimov said. "But it's a good thing -- we (found) a way to score after (giving up the three straight goals), and get it done and get the two points for us. It's most important thing."

Hossa, who became the 44th player in NHL history to reach the 500-goal plateau, left the game in the third period after being hit by a puck while blocking a shot. Hossa left the Blackhawks bench and watched his team's furious finish from the dressing room.

"It's tough to give up four goals in a row obviously," said Hossa, who said he was OK after being forced from the game. "That's a lesson for us. But on the other hand, we end up winning the game which is huge and it's a big victory."

Hossa's milestone goal gave Chicago a 4-0 lead after the veteran right-winger came with only three seconds remaining on a power play at 5:04 of the second period. Hossa received a standing ovation after the score, which chased Flyers' starting goalie Michal Neuvirth in favor of Steve Mason. Neuvirth gave up the four goals on 16 shots.

"Obviously, doing it at home in front of our fans, I couldn't be happier," Hossa said.

But the Flyers erased a four-goal deficit after Wayne Simmonds pounded a power-play rebound past Corey Crawford with 3:49 gone in the third period. Philadelphia (1-1-1) got to within 4-3 with a pair of goals in a span of 1 minute, 17 seconds after entering the period trailing by three.

"We've always been a team that's been able to come back," Simmonds said. "Obviously, that's not the situation you want to be in but we made a good push, but we turned the puck over a couple too many times."

Matt Read scored his second goal of the night just 37 seconds into the third period before Sean Couturier followed with a backhand that got past Crawford, who finished with 23 saves.

Philadelphia got to within 4-1 with 1:37 remaining in the period when Read scored on a power-play goal as the Blackhawks' penalty-killing unit's season-long struggles continued.

The late score sparked the Flyers over the first 10 minutes of the third period before the Blackhawks responded with the three straight goals.

"I think we have a positive vibe on the bench and things were just going who was going to get the next lucky bounce," Read said.

The Blackhawks got the bounce they needed when the Philadelphia turnover led to Anisimov's go-ahead goal.

"We'll take the win," Blackhawks' coach Joel Quenneville said.

The Blackhawks used a first-period scoring flurry to build a 3-0 advantage. After being held without a goal for the first three games of the season, Patrick Kane used a wraparound goal off a rebound 56 seconds in to give Chicago a 1-0 lead.

Dennis Rasmussen extended the lead later in the period after he took advantage of defenseman Ivan Provorov losing his footing in the Blackhawks zone. Panarin finished off the first-period scoring 13 seconds into a power play when he took a pass from Brent Seabrook and fired a one-timer past Neuvirth.
