UNIONDALE, N.Y. -- New York Islanders goaltender Rick DiPietro is expected to miss the next 4-to-6 weeks with facial fractures suffered in a fight Wednesday.

In the waning moments of a 3-0 loss to the Penguins, DiPietro squared off with Pittsburgh netminder Brent Johnson. The bout didn't last long as Johnson floored DiPietro with one left hook.

The 29-year-old, who also suffered knee swelling because of the incident, doesn't regret getting into the fight.

"I'm sick of losing. Our team is sick of losing," DiPietro said Friday while addressing the media. "You never go into a fight expecting that you're gonna get smashed in the face that hard or with these kind of consequences. It happens. [Johnson] landed a good punch and you move on."

DiPietro is 7-10-4 in 21 games this season with a 3.36 goals-against average and .890 save percentage for the Islanders, who are last in the Eastern Conference.

The top overall pick in the 2000 draft, DiPietro was limited to just 13 games over the previous two seasons because of knee problems.
