Anaheim Ducks rookie Leo Carlsson will miss approximately four-to-six weeks with an MCL sprain, the team announced Saturday.

Carlsson left Thursday's contest against the Calgary Flames and didn't return after opposing defenseman MacKenzie Weegar fell awkwardly on his leg.

The Ducks drafted Carlsson, who turns 19 on Boxing Day, second overall this past summer. He's registered 15 points in 23 games throughout his debut season and has routinely been held out of the lineup for load management.

Anaheim entered Saturday's action sitting 29th in the NHL at 12-20-0.
