Klefboom is weighing all the possibilities to deal with injuries from last season, including surgery, per Elliotte Friedman of Sportsnet.
The specifics of the injuries are unclear, but the possibility of surgery would keep the Swede out for an extended period of time. Klefbom supplied two assists while averaging 24:13 of ice time in the NHL's bubble, so his absence would be a major loss for the Oilers should he opt for surgery.
