Evgeni Malkin scored in his return from a lower-body injury, Sidney Crosby added his 16th goal, and the host Pittsburgh Penguins beat the Columbus Blue Jackets, 2-1, on Monday night.
Malkin missed two games last week.
Penguins forward James Neal was suspended five games for kneeing Boston Bruins forward Brad Marchand in the head during the Bruins' 3-2 win Saturday.
The NHL salary cap is expected to rise to about $71 million next season, an increase of more than 10 percent.
