Alaska hockey teams are urging fans to help after a crash that killed more than a dozen people Friday in Canada, where a tractor-trailer slammed into a bus carrying a youth hockey team.

Flowers and other tributes filled the Elgar Petersen Arena where the Humboldt Broncos called home. All they and the families of the team have left now are the memories.

Players are among the 15 people confirmed dead in Friday's bus crash in Nipawin, Saskatchewan, where the Broncos had traveled for a playoff game in the Saskatchewan Junior Hockey League.

The Broncos' head coach and bus driver are among the dead. Fourteen others survived, and have various injuries.

Even though the Broncos played in a rival league, that doesn't matter to the Fairbanks Ice Dogs and the rest of the North American Hockey League. They ask fans to donate to a fund to help the families of the victims.

The Ice Dogs' general manager, Rob Proffitt, called the crash a "tragedy" to which any team can instantly relate.

"It's still pretty hard for me, it's my worst nightmare as a GM of a hockey team when you go to bed at night (and) your team is traveling -- still pretty hard to get my head around," Proffitt said.

Investigators say it's still too early to say what caused the crash.
