An encounter in 2003 with a dog led to a painful injury for Jon Grayson, now 24, of Houston, Texas, but not in the way most might guess.
"I tripped over my mom's Chihuahua while I was at home," he said. "I didn't even see her; she's a little-bitty thing."
The stumble led to an aggravation of the broken left ankle Grayson had suffered a year and a half prior to the accident. And it was severe enough to sideline him from the University of Texas ultimate Frisbee team for two weeks.
