US swimmer Ryan Lochte to appear on ESPN's 'College GameDay' panel

United States swimming Olympic champion Ryan Lochte is reportedly expected to appear on ESPN's College GameDay this Saturday before the Florida Gators and South Carolina Gamecocks go head to head in an American Football clash.

The 28-year-old, who has made a number of media appearances following his success at the London 2012 Games in the summer, will be the 'celebrity picker' of the day, where he will choose who he thinks will win in all of the college games that weekend.

Lochte will appear alongside regular hosts Chris Fowler, Lee Corso, Desmond Howard and Kirk Herbstreit for the pre-show this Saturday, according to reports.

Meanwhile, Lochte will make his television sitcom debut in an episode of 30 Rock in the US tonight.
