Ullstrom out 3-4 weeks

Islanders forward David Ullstrom is expected to miss three to four weeks with a groin injury, the team announced Friday afternoon.

Ullstrom sustained the injury in Thursday's 2-0 win against the Tampa Bay Lightning; the 23-year-old Swedish winger exited the game during the third period and did not return.

It's been a frustrating year for Ullstrom, who has two goals and three assists in 20 games for the Isles. He's made some promising strides but also struggled to seal his spot in the lineup.

Just last week Ullstrom was scratched against the Rangers. He was then sent down to Bridgeport, where he scored the overtime game-winner before being recalled to replace an injured Michael Grabner.
