Prince Harry will attend the Army Navy match at Twickenham on Saturday as Patron of the Invictus Games Foundation.
The Army Navy Match is the annual rugby union match between the senior XV teams of the Royal Navy and British Army.
Harry's Invictus Games Foundation is the official charity of the day for this year’s match.
This year is 100th fixture since the unions were formed and marks the culmination of the annual Inter-Services Competition.
Harry will be joined on the day by competitors from the 2014 and 2016 Invictus Games, as well as some of those hoping to be selected for the third Invictus Games in Toronto.
Friends and family have also been invited to "recognise the vital contribution this close support network plays in a competitor's recovery journey."
