'March Madness' - NCAA Four Take Seedings.

Defending champions Florida have been given one of the top seedings in the NCAA tournament on Sunday, along with Ohio State, Kansas and North Carolina. All four teams booked their positions by winning their conference tournament championship games.

The tournament involving sixty-five teams, known as 'March Madness' begins on Tuesday night in Dayton, Ohio, with a play-in game between the two lowest ranked teams. On Thursday afternoon, it's action all the way on the court.

The Gators aim to become the first repeat champions since Duke in '92. Florida, which won the football championship in January, will begin its bid for another title in the Midwest region with a game on Friday against Jackson State in New Orleans.
