Jonah Lomu is to play in a charity rugby match at Twickenham to raise funds for the care and rehabilitation of British military personnel wounded in Iraq and Afghanistan.
Lomu will play for an International XV against a Help for Heroes XV in the match on 20 September.
Lomu, 33, won 63 caps for the All Blacks before illness cut short his career.
Former Wales centre Scott Gibbs will skipper the International team with Lawrence Dallaglio leading the other side.
England's World Cup-winning captain Martin Johnson will play alongside Dallaglio.
