PITTSBURGH -- Toronto Maple Leafs forward Joffrey Lupul fractured his forearm in Wednesday night's 5-2 win over the Pittsburgh Penguins and is expected to miss a minimum of six weeks, the team announced Thursday.
Lupul has been placed on the Leafs' injured reserve list.
The 29-year-old Lupul was in front of the net during a power play midway through the second period when a slapshot from teammate Dion Phaneuf smashed into his arm. Lupul left the game immediately and did not return.
Coach Randy Carlyle said Lupul would be re-evaluated on Thursday before Toronto returns home to face the New York Islanders.
"It's tough but what can you do, you've got to move on," forward Clarke MacArthur said after the game.
Lupul signed a five-year contract extension with the Maple Leafs on Sunday. He led Toronto with 25 goals and 42 assists last season and made his first All-Star team. Lupul had yet to score for the Maple Leafs this season at the time of the injury.
In Lupul's place, forward Matt Frattin has been recalled from the Toronto Marlies of the American Hockey League.
Frattin has played 21 games for the Marlies this season, collecting 17 points on nine goals and eight assists, along with 14 minutes in penalties. On Wednesday, he was added to the Western Conference roster for the 2013 AHL All-Star Classic.
Frattin is expected to make his season debut with the Leafs on Thursday night against the New York Islanders at Air Canada Centre.
