Justin Gatlin, Asafa Powell to go head-to-head at Franklin Field

NOTE: Click here to read about Villanova's triumph in the men's college Distance Medley Relay Championship of America.

2004 Olympic gold medalist Justin Gatlin will race on American soil for the first time since his doping band ended on a track that he knows very well.

Gatlin was a star at the Penn Relays for the United States and the University of Tennessee, but he hasn't been to Franklin Field since he was banned for four years for doping in 2006 by the International Olympic Committee.

Lining up across the track from Gatlin will be another of the sport's most famous names: Asafa Powell. Gatlin and Powell will be the opening sprinters for USA Blue and Jamaica, respectively, in Saturday's USA vs. the World men's 4x100 relay.

The official start lists for all of the USA vs. the World races were released Friday evening. We knew which runners were coming, and now we know how and when they'll line up.

Of course, there is one really big name missing: Usain Bolt. The word got out late Friday night, though, that Bolt might be at Franklin Field nonetheless. ESPN track color commentator Ato Boldon tweeted that Bolt "is here but not running. May join us in the booth" during the telecast, which will air tape-delayed from 8:00 p.m. to 10:00 p.m. on ESPN2.

If Bolt does show up, even if he doesn't run, it would create quite the stir. Stay tuned.

For now, here are the USA vs. the World start lists. Afterwards, you can watch a video preview of the USA vs. the World events with me and The Inquirer's Joe Juliano.

When we shot the video, we didn't know what the start lists would be, and we honestly didn't think we'd find out until the morning. There's a history of runners pulling out at the last minute for various reasons.

So excuse us for that, and get ready for what is going to be an electric Saturday at Franklin Field.
