"There's always the grey area of how injuries heal, but that's typical," Jets head coach Paul Maurice said of Byfuglien's timeline.
And first-line centre Bryan Little will miss at least the early part of Winnipeg's upcoming four-game road trip with an upper-body injury, Maurice said after Friday's practice.
"Bryan Little's going to make the trip," Maurice said. "I don't expect him for the front end of that, and maybe longer than this trip.
"There's a chance he plays toward the end of it, and there's a chance that he doesn't. We'll know more in probably five to seven days on that."
Defenceman Mark Stuart left practice after being struck in the face by a puck. Maurice said he thought Stuart was OK but he'd know better after the player was checked out.
Byfuglien left Winnipeg's 3-1 loss to Ottawa on Wednesday in the second period. The defenceman appeared to be favouring his right arm.
Little has been given some practises off this season to rest but Maurice said he was injured in the game against Ottawa.
"He played through it, came back a little bit more sore the next day," said Maurice, whose team had Thursday off.
Winnipeg (32-21-12) starts its road trip against Nashville (41-18-7) on Saturday.
The Jets currently hold the Western Conference's second wild-card spot with 76 points, one behind Minnesota.
