The governing body of athletics will not make any changes to the false start rule at the end of the World Championships in Daegu.
The rule - which sees any athlete making a false start disqualified - led to world record holder Usain Bolt missing the 100m final.
Bolt's exit led to talk that the IAAF could amend the rule.
But a senior IAAF source has told the BBC that the rule will not be discussed in a meeting on Sunday.
IAAF vice-president Bob Hersh had earlier stated that no action should be taken until further talks.
He said: "It would be a mistake to quickly reverse the decision."
Any changes could be made in time for next year's Olympics in London.
