LAKE DELTON, Wis. (AP) — Junior league hockey players sickened by an apparent carbon monoxide leak at a Wisconsin rink over the weekend are taking the day off from practice.

Authorities have blamed an ice resurfacing machine for a suspected carbon monoxide leak that sent dozens of people to hospitals Saturday. The leak was discovered after players and others began feeling ill at a Lake Delton ice rink during a game between the Dells Ducks and Ice Hawks from Rochester, Minnesota.
