Bolt and Gay to race in Brussels after worlds

Sprinters Tyson Gay (R) of the U.S. and Usain Bolt of Jamaica pose together at a news conference in New York May 29, 2008.

RALEIGH, North Carolina (Reuters) - Triple Olympic champion Usain Bolt will race chief rival Tyson Gay at Brussels on September 4, Gay's manager told Reuters on Wednesday.

"It will likely be a 100 (meters) but it is confirmed they will race," Mark Wetmore said in a telephone interview.

Discussions also are under way for the two to race in Zurich on August 28, Gay and Wetmore said in a separate teleconference with U.S. reporters.

The distance in Zurich is to be determined, Wetmore said.

"There have been a couple of discussions," Gay said. "Mark says people really want to see a one-off race (between the two).

Jamaican Bolt and American Gay, who have not met on the track this year, are expected to be the major draw of the August 15-23 world championships in Berlin. Both are scheduled to run at 100 and 200 meters.

Bolt set world records in both sprint events at the Beijing Olympics.

Gay, the 2007 double sprint world champion, did not appear in either final. He failed to qualify for the 100 meters championship race and did not compete in the 200 at Beijing because of a hamstring injury at the U.S. trials.
