The American competition is the world's largest single-sport event for athletes with disabilities, and makes its ninth stop in the US state of Kentucky for its 68th edition.

This year's event, due to be held from April 7 to 10 in the South Hall of the Kentucky Exposition Center, is set to feature 976 athletes across five divisions - Junior National Invitation Tournament (NIT), Junior Prep, Junior Varsity, Championship Division and Division III. 

The adult divisions, Championship and Division III, are each made up of 40 teams that will battle for a coveted national crown. 

The Championship Division, the nation's elite athlete category with 16 teams, will play over a three-day period in the hope of playing for the title on April 9.

The Division III teams, the NWBA's recreation division, will be aiming to reach their national title game on April 10.

Seeded number one in the Championship Division is the Dallas Mavericks, followed by the Milwaukee Bucks.

The New York Rollin' Knocks and Rogue Valley Scorpions are the number three and four seeds respectively, while the Bay City Thunder moved up into the number five seeding.

The Division III teams will be led by number one seeded TIRR Hotwheels, with the Ft. Lauderdale Sharks sitting on the other side of the bracket in the number two position.

The Delaware Destroyers secured the number three seeding, while the Nassau Kings and Charlotte Rollin Hornets A round out the top five.

For the first time since 1998, the Junior Prep division - for athletes aged 13 and under - will feature a full compliment of 16 teams for its three-day double-elimination tournament.

The Junior Varsity and Junior NIT divisions, for high school aged children, features 32 more squads.

The National Wheelchair Basketball Tournament will feature a total of 176 games on 12 courts.
