Rantanen (ankle) will be out 2-4 weeks, Mike Chambers of the Denver Post says.

EDGE Analysis

The Avalanche have said Rantanen has a sprained ankle, and he has been seen in a walking boot with crutches since injuring the ankle Friday. He bounced between the AHL and NHL last season, so it's unlikely he would've had a big fantasy impact this season, but he could make it back in time for the season opener on October 15.
