The forward was injured while throwing a football around with teammates in the end zone of Mosaic Stadium as they waited to practice in preparation for the 2019 Tim Hortons NHL Heritage Classic against the Calgary Flames on Saturday (10 p.m. ET; NBCSN, CBC, SN1, CITY, TVAS, NHL.TV). The Jets do not believe Appleton will require surgery, coach Paul Maurice said.
Appleton played in Winnipeg's first nine games this season but was a healthy scratch the past two. He does not have a point and is averaging 10:21 of ice time.
The 23-year-old played 36 games for the Jets last season, his first in the NHL, and had 10 points (three goals, seven assists).
Maurice said he felt bad for Appleton.
"When you think about the time a man like that would have put in trying to make this team and try to grab a spot, the amount of commitment he would have put in and, as I have said, his numbers are outstanding to get here and to get that opportunity," Maurice said.
