"Put him to sleep," Lundy said.
He left the student on the ground and took off for football practice. Twenty minutes into practice, someone approached the football coaching staff.
"There is someone knocked out in front of the school," he said.
Lundy heard him. He left football practice and ran straight home to his uncle.
The next week, Lundy began boxing training.
After a relatively brief career as an amateur, the 28-year-old Lundy has used that tenacity he showed on the school yard in the ring. He has racked up a 22-1-1 record as a professional and is the second-ranked lightweight boxer by the World Boxing Council.
At 10 p.m. Friday, Lundy will take on Raymundo Beltran (25-6) at Resorts Casino Hotel in Atlantic City. ESPN2 will carry the 10-round bout live.
"All the work is done. I've trained like a warrior," Lundy said. "I've seen him fight a couple times. He's kind of slow - doesn't throw many punches. To a guy like me with quick hands, that plays to my advantage."
