Avalanche's Rantanen out 2-4 weeks with ankle injury

Mikko Rantanen's quest to make the opening-night roster has hit a bump in the road.

The Colorado Avalanche forward injured his ankle during a rookie-tournament game and is expected to be out two-to-four weeks, thereby missing a good chunk of training camp.

The 19-year-old, drafted 10th overall in 2015, recorded 24 goals and 36 assists in 52 AHL games last season, his first in North America. He was, however, held pointless in his first nine NHL appearances.

Rantanen is considered to be an important piece of Colorado's future - if not its present - and a speedy recovery would benefit both parties.
