UNDATED (AP) — The Pittsburgh Penguins' run at a record-breaking streak is over. Playing without injured star Sidney Crosby, the Penguins fell to Buffalo 4-1 to end their 15-game winning streak.

Kevin Porter scored his first two goals of the season for the Sabres, who won for the first time in five games. Steve Ott and Cody Hodgson also scored as Buffalo sent Pittsburgh to its first loss in more than a month.

Jarome Iginla scored his first goal with the Penguins after coming over in a trade with Calgary last week but it wasn't nearly enough.

The loss left the Penguins two wins short of the NHL record for consecutive victories.
