Toronto Maple Leafs center Calle Jarnkrok is considered month-to-month after undergoing groin and sports hernia surgery, the team announced Monday.
Jarnkrok, 33, has not played in a game this season.
He tallied 21 points (10 goals, 11 assists) in 52 games last season for the Leafs.
The 2010 second-round draft pick has 301 career points (136 goals, 165 assists) in 699 games played for four teams, most notably the Nashville Predators (2013-21).
Jarnkrok is in the third season of a four-year, $8.4 million contract in Toronto.
