Former 100-metre world record holder Asafa Powell and 2004 Olympic 100 metre champion Justin Gatlin will lead a stellar 50-metre field at the US track and field open event in New York later this month.
Jamaica's Powell, Americans Gatlin and Trell Kimmons, Richard Thompson of Trinidad and Tobago and Antigua's Daniel Bailey will compete in the seldom-run event on January 28 at Madison Square Garden.
Powell will make his first indoor appearance since 2004 at the meet.
Gatlin won 2005 world 100 and 200 titles but his feats were tainted after a four-year ban was imposed following a positive test for testosterone.
Thompson was second to Usain Bolt at the Beijing Olympics while Bailey took third at 60m in the 2010 world indoor championships.
The 50 metre world record of 5.56 seconds was set in 1996 by Canada's Donovan Bailey.
