MacKinnon reportedly suffered broken nose in collision with Hall
The team expects to have a clearer timeline for his recovery in the coming days as he's still being evaluated, Kaplan adds.
MacKinnon was ruled out of Wednesday's contest against the Boston Bruins after a big collision with Hall during the opening period.
The Bruins forward knocked the shaft of MacKinnon's stick with his shoulder as the center tried to exit the zone, hitting MacKinnon in the face and causing him to fall hard to the ice.
The 26-year-old was bloodied on the play but managed to skate off on his own. Referees initially charged Hall with a five-minute penalty. However, they ended up handing the 30-year-old a two-minute infraction for interference following a review.
A major penalty can't be rescinded and can only be reduced to a lesser penalty of the same infraction, according to Daily Faceoff's Frank Seravalli.
The Avalanche made their displeasure with Hall known in the second period. Defenseman Erik Johnson received a penalty after cross-checking Hall three times behind the net in Colorado's zone.
MacKinnon has recorded nine goals and 34 assists in 31 games this season.
