GLENDALE, Ariz. -- Arizona Coyotes defenseman Michael Stone will miss the remainder of the season, and captain Shane Doan is out against the Calgary Flames at Gila River Arena on Monday (10 p.m. ET; SNF, FS-A, NHL.TV).
Stone sustained a left knee injury in the third period of a 2-1 win against the Philadelphia Flyers on Saturday when he got tangled with Flyers forward Michael Raffl with 8:37 remaining.
The Coyotes are awaiting test results to confirm the initial diagnosis.
"It's longer term than the season has left in it," coach Dave Tippett said. "I would say he would be done for the season."
Stone is second in scoring among Coyotes defensemen with six goals and 36 points.
Doan is day-to-day after leaving at 6:07 of the third period following a hit into the boards from Flyers defenseman Radko Gudas. Doan leads the Coyotes with 26 goals and is third with 44 points.
