The hockey world runs in small circles.

Prior to Wednesday's AHL match between the San Diego Gulls and Tucson Roadrunners, the Gulls unveiled a "14" decal on their players' helmets, honoring the jersey number of Roadrunners captain Craig Cunningham, who collapsed earlier in November.

Cunningham remains in a Tucson hospital and is in critical but stable condition.

The Gulls are the farm team of the Anaheim Ducks, while the Roadrunners are the minor-league affiliate of the Arizona Coyotes.
