JACKSONVILLE, Fla.- The man behind Ozzie Osprey is flying the coop.

Matt Biegun, who has worn the UNF mascot's costume for the past nine years, announced his retirement via Facebook Thursday.

The Ospreys were a NCAA Division Two program when Biegun first started out as Ozzie. Now they are a Division One school just one year removed from their first ever NCAA men's basketball tournament appearance.

"I do not know when it will be my final day, but I do know that not a day goes by without me knowing how absolutely blessed I’ve been to do something I love." Biegun said via Ozzie's Facebook page.

Tryouts for the new Ozzie will take place later this year.
