SILVER CITY, N.M. (AP) — Several riders were injured as a crash stalled the first stage of the annual Tour of the Gila in southwestern New Mexico.

Race spokeswoman Rebecca Reza says three riders were sent to a hospital in Tucson, Arizona, and at least six were treated locally.

Officials initially said at least a dozen were injured. Reza said later Wednesday night that while 14 aren't racing Thursday and most of them were injured, she listed nine riders who had so far been confirmed to have injuries.

She says riders sent to Tucson included one with a knee injury and two others whom she only described as "no serious injuries, conscious and coherent."

Some of the injuries to other riders included hand and knee problems.

It's unclear what caused the pileup as the riders raced more than 70 miles from Silver City to the ghost town of Mogollon.
