Tokyo — Britain's Royal Family is getting excited about England's appearance in the Rugby World Cup final — even its most recent arrival.

Prince Harry has sent a message of support to the England squad ahead of their title match against South Africa in Yokohama on Saturday.

Included in the message was a photo of the prince's 5-month-old son, Archie, in an England jersey.

"A nice touch," England flanker Sam Underhill said Friday.

Harry is a long-standing England fan and a patron of the Rugby Football Union. He will be attending the final this weekend.

This not the first time the the Duke of Sussex publicly supported the team. After the team won the match against New Zealand's All Blacks, Prince Harry took to Instagram to congratulate them.
