Huddlestone had agreed to play in the match at White Hart Lane to honour club legend King but has the slight inconvenience of preparing for an FA Cup final five days later.
"I have had a few texts," said Huddlestone, who spent eight years at Tottenham before leaving for Hull last summer.
"When I said I wasn't able to play in Ledley's testimonial a few people told me as long as we beat Arsenal all would be forgiven.
"It will add a bit of satisfaction if we do win it but primarily it's about Hull winning the cup and me having a trophy on the CV."
