Pettersson produced a power-play assist and three shots on goal in Friday's 3-2 win over the Jets.
Pettersson ended a four-game point drought by setting up Oliver Ekman-Larsson for the opening tally. The 23-year-old Pettersson has shown glimpses of his talent this year, but he's struggled to 10 points (six on the power play), 49 shots on net and a minus-2 rating in 18 contests overall. That's led to the Swede centering the third line and playing on the second power-play unit, though those changes will probably be temporary.
