PITTSBURGH (AP) _ Jaromir Jagr's 15-game scoring streak ended Tuesday night as strained his groin during the first period of the Pittsburgh Penguins' 3-2 win over Buffalo.

Jagr, who leads the NHL with 33 points in 16 games, had three goals and six assists in his previous six games and was chosen Monday as the NHL player of the week.

Jagr, the two-time defending NHL scoring champion, was averaging 2.2 points per game _ the best average over a sustained stretch since Wayne Gretzky averaged 2.3 points over 25 games in 1990-91.

Jagr missed most of the Penguins' first-round playoff upset of the New Jersey Devils last spring with a groin injury, but played throughout the second round against Toronto.

He missed only one regular-season game last season.
