Pecker is a key witness in the case against the former US president, who is accused of falsifying business records to cover up hush-money payment
“Tyson has scratched from the 100,” the world silver medallist’s agent Mark Wetmore said in a statement.
“He was unable to warm up due to a hip and adductor problem on his right side.”
Wetmore also told Reuters that Gay would not try to run in the 200m trials beginning on Saturday.
Gay could be a part of the U.S. world 4x100m relay team if he recovered in time, USA Track and Field officials said.
Only the top three finishers in each event at the U.S. meeting qualify for the world championships in Daegu, South Korea, in August.
The world’s second fastest man, Gay has been troubled by hip and adductor problems for some time. He had earlier cast doubt on competing in the 200m at the U.S. trials because of the problems.
A much-anticipated showdown in the 100m between Bolt and Gay had been set to be the highlight of the world championships due to the rarity of the sprinters’ meetings.
World champion in the 100 and 200m in 2007, Gay missed a 100m clash with Bolt at the 2008 Beijing Olympics after not qualifying for the final, having failed to fully recover from an injury in U.S. 200m trials.
The two met in the 2009 world championships with Bolt winning in a world record 9.58 seconds. Gay took second.
They raced again in Stockholm last year with Gay taking a shock victory.
