The Winnipeg Jets are hurting on defence.

The team announced Thursday that they have lost defenceman Zach Bogosian for four to six weeks with a lower-body injury, Tobias Enstrom for the rest of December with an upper-body injury and Grant Clitsome for two weeks with an upper-body injury.

Bogosian suffered the injury Wednesday night against the Edmonton Oilers while Enstrom has missed the last four with his injury.

With the downed players, Dustin Byfuglien will be moved from forward to defence for Friday night's game against the Colorado Avalanche.
