The news was first reported Monday by Columbus Dispatch writer Shawn Mitchell.
If the timeline on the injury is accurate, Umberger won't return this season unless the Blue Jackets qualify for the Stanley Cup Playoffs. They have four games remaining, and currently lead the New Jersey Devils and Toronto Maple Leafs by three points and the Washington Capitals by four points for the second wild-card spot in the Eastern Conference.
Umberger had been a healthy scratch several times in recent weeks. He scored 18 goals and 34 points in 74 games this season.
It's pretty crazy, but believe me when I say we didn't draft these players with the mindset we had to because they had good hockey-playing dads. It just turned out that way. But we're certainly glad they're a part of our organization.
