RALEIGH, North Carolina (Reuters) - Olympic and world sprint champion Usain Bolt will not decide until July whether he will compete in October's Commonwealth Games in New Delhi, his manager told Reuters Saturday.

"I have no idea," Simms said when asked whether Bolt was to likely compete in the October 3-14 Games. "The decision will be made in July by coach (Glen) Mills."

Bolt has said his biggest goal in 2010 would be to go undefeated on the new Diamond League circuit and Simms confirmed the 23-year-old planned to run in seven meetings on the circuit as well as several races in Jamaica.

The Jamaican is expected to face American world silver medalist Tyson Gay, the second-fastest 100 meters runner of all-time, at least three times on the new circuit.

His compatriot Asafa Powell, the former world record holder, is also likely to join the pair in several races.

"With three great athletes in one race, anything is possible," said Bolt, who lowered his world records to 9.58 seconds in the 100 meters and 19.19 seconds in the 200 at August's world championships in Berlin.

"I am going to be hard to beat if I am in shape," added Bolt, who did not lose a final in 2009. "But if I get beat, I would not be surprised."

Bolt did not compete at the 2006 Commonwealth Games in Melbourne because of a hamstring injury.
