Kane will be re-evaluated in two weeks, Maurice said, and will monitored on a week-to-week basis after that.
Maurice said he was initially fearful the injury was more serious. "To be quite honest with you, it's actually better news than I was expecting," he said.
Kane was injured during the first period of Winnipeg's season opener against the Coyotes. He played only 1:24 before he collided with a teammate and was forced from the game.
Kane, 23, scored 41 points last season, the seventh-most on the Jets. He scored 30 goals as a 20-year-old in 2011-12.
