Jeff Demps, the former Groveland South Lake and University of Florida track and football star, will compete in the Olympics Friday.
Demps will be running the lead leg in the preliminaries of the 4x100-meter relay, his agent Nohemy Baltodano said.
"I was very excited," Demps said in a statement released through Baltodano. "This is an opportunity of a lifetime."
Demps missed out on a chance to compete as an individual at the Games when he finished seventh in the 100-meter dash at the U.S. Olympic team trials in June. He was added to the 4x100 relay pool just before the Olympics as a replacement for Mike Rodgers, who has a stress fracture in his left foot.
Baltodano said the team will line up with Demps running the lead leg, followed by Darvis Patton, Trell Kimmons and Ryan Bailey on the anchor.
If the U.S. qualifies for Saturday's final, the lineup will probably include Justin Gatlin and Tyson Gay, who both train at Clermont's National Training Center. Gatlin won a bronze medal in the 100-meter dash and Gay finished fourth.
