Another half dozen 2005 World Championships medalists have been added to the field for the 11th annual Reebok Boston Indoor Games, organizers announced Tuesday. They join three reigning World Champions - Tirunesh Dibaba, Lauryn Williams and Adam Nelson - already scheduled to compete.

The first stop on USATF's 2005 Visa Championship Series, the Reebok Boston Indoor Games will be televised January 29 from 3-4:30 p.m. Eastern Time on ESPN2.

Making the trip to Boston for the event, set for Jan. 28, will be Americans Bershawn Jackson, the 400-meter hurdles World Champion; Andrew Rock, a double World Champs medalist (400m silver, 4x400m gold); and Chaunte Howard, the high jump silver medalist. Also set to compete are 2005 Visa Champion Angela Daigle-Bowen, 2005 USA 100m champion Me'Lisa Barber and 2004 Olympian Muna Lee, who along with Williams made up the entire USA gold-medalist 4x100m relay team at the 2005 World Championships in Helsinki.

Headlining the boys' elite, international Junior Invitational Mile will be A.J. Acosta of Oceanside, Calif., the 2005 Foot Locker Cross Country Champion.

They bolster a star-studded roster for this year's Reebok Boston Indoor Games that includes at least 29 Olympic and World Championships medalists, highlighted by four reigning individual World Champions.

Over the past decade, the Reebok Boston Indoor Games, produced by Boston-based Global Athletics & Marketing, Inc., has played host to 89 Olympic and World Championship medalists, and has been the site of four World Records and eight American Records. For the past three years, the event has been sold out.
