A tournament at the Santa Barbara polo club in California, where he plays, is due to take place on the days before and after his father’s May 6 crowning in London.
Sources say Harry has not yet confirmed whether he will take part in the matches on May 5 and 7.
And club officials yesterday declined to comment on the issue.
If his four-man team Los Padres does play they could find a sub to replace him for any games he misses.
A source said: “The club has received no word yet on Harry’s plans for the tournament.
“But he’s expected to play again this season.
“The speculation is that Harry will be returning for the coronation so probably won’t be taking part in the polo that weekend.”
