FIFA boss Gianni Infantino had invited the boys' Wild Boars football team to Sunday's World Cup final last week.
But FIFA said it had been informed "that due to medical reasons, the boys will not be in a position to travel to Moscow".
"FIFA's priority remains the health of everyone involved in the
operation and we will look into finding a new opportunity to invite the
boys to a FIFA event to share with them a moment of communion and
celebration," a spokesman said.
The Thai footballers, aged from 11 to 16, had been stuck deep
underground after setting off to explore the cave with their coach after
training on June 23.
FIFA also expressed condolences to the family of a Thai Navy SEAL who
died after running out of oxygen during the rescue operation on Friday.
"Our thoughts are with his family," FIFA said.
