The Jamaican, who won the 200 metres at the 2004 and 2008 Olympics and was a member of the team that claimed the 4x100 metres title in Athens, has said that the event, which is due to open on October 3, does not fit in with her schedule.

Her agent Claude Bryan told the Jamaica Observer that she is almost certain to join the likes of Britain's world heptathlon champion Jessia Ennis in missing the event.

He said: "Well currently, I don't think it will be a go.

"We haven't sat down and made a final decision, but given the time of the year that it is, I just can't see it happening with the World Championships coming up next year."

It is another embarrassing setback for Suresh Kalmadi, the chairman of the Delhi 2010 local organising committee, who in December had claimed that Campbell-Brown's team-mate Usain Bolt would definitely run in the Commonwealth Games only for his agent to say that such no such decision had been made.

Kalmadi has been hoping that the presence of a strong Jamaican team, who finished second in the medals table at the World Championships in Berlin last year with 13 medals, to help lift the standard of the event.

Campbell-Brown, who won the 60m at the World Indoor Championships in Doha earlier this month, finished second in the 100m and 200m at the 2002 Commonwealth Games in Manchester.
 
But her main focus is on next year's World Championships in Daegu, South Korea.

Anthony Carpenter, her American-based coach, told the Jamaica Observer: "Our goal this year is to basically make her as competitive as possible in the 100m and then maintain the position that she's had in the 200m for the last couple of years.

"There is a few women in front of her in the 100m right now and we want to be a player at the level where they are at this point in time, so we know 10.85secs is not going to get it done and we're focused on running faster than she's run before."
