FORNEY, Texas (AP) _ Nine high school students and two coaches were injured after lightning struck during football practice Tuesday, authorities said.

Jeff Place, a nurse at Baylor University Medical Center, said one student suffered cardiac arrest at the scene and was in critical condition.

``If this kid makes it, it's probably due to some fast acting by the coaches'' who administered cardiopulmonary resuscitation, Police Chief Rick Barnes said.

The other students were in stable condition, Place said. The coaches were in stable condition and were expected to be released from The Medical Center of Mesquite, nursing supervisor Carolyn Grinstead said.

About 100 people were on the field at Forney High School when a storm suddenly erupted shortly before 4 p.m., Barnes said.

``They were in the process of getting kids off the field and _ boom _ it hit,'' he said. ``There had been some dark clouds and a bit of a rumble prior, but the lightning struck all at once.''

Forney is 20 miles east of Dallas. The Forney Jackrabbits start their season Sept. 8.
