Jeff Demps has an Olympic silver medal. The U.S. track star now wants to make a run at a Super Bowl ring.

Agent Daniel Rose tells The Associated Press late Wednesday night that several NFL teams are interested in signing the speedy Demps, a former running back at the University of Florida. Rose says Demps is expected to make a decision by Thursday night. He went undrafted in April.

Tampa Bay coach Greg Schiano confirmed that the Buccaneers are interested in Demps, who was part of the 400-meter relay team that finished second to Jamaica in London. The New York Jets, with Demps' former college teammate Tim Tebow, also are among the teams in the mix.
