A team spokesperson confirmed that Sedin took a flight home. The 31-year-old native of Ornskoldsvik, Sweden was forced to miss a game in Dallas later Thursday.
He was sidelined in the first period of Vancouver's 2-1 overtime loss in Chicago following a hit by Duncan Keith. The Blackhawks defenceman received a two-minute elbowing penalty for the infraction, which occurred in mid-ice away from the puck.
Sedin played one shift during the power play while Keith was off, but then went to the dressing room and remained out the rest of the game.
Sedin has 30 goals and 37 assists this season and won the NHL scoring title in 2010-11. The team spokesperson said she could not provide an update on his condition. Canucks coach Alain Vigneault told reporters in Dallas that head athletic trainer Mike Burnstein decided to send Sedin home after checking him out Thursday morning.
Vigneault said he did not speak to Sedin on Thursday and had no new information on him.
It's the first significant injury for Sedin since he missed 18 consecutive games with a fractured foot midway through the 2009-10 season. He also sat out another contest later in the campaign.
Note: The Canucks close out their four-game road trip Saturday in Denver.
