Former All Black star Sonny Bill Williams has made himself available to New Zealand for the Rugby League World Cup.
Williams was not named in coach Stephen Kearney's 24-man squad on Monday, with the selectors citing the player's "other commitments."
But Williams has since insisted he wants to help the defending champions defend their title, handing Kearney a potential selection headache.
The maximum number of players in a World Cup squad is 24, so if Williams was to be included he would need to replace another squad member.
Kearney said: "Late on Tuesday, Sonny Bill Williams expressed his desire to play for the Kiwis in the Rugby League World Cup.
"Our thinking had always been that, if Sonny was available, he would be part of the team.
"We are now exploring options around Sonny's possible inclusion in the tournament. This would require ratification by the World Cup organisers."
Williams made a brilliant return to league this year with newly-crowned NRL champions Sydney Roosters.
It had been rumoured he was returning to union but his decision to make himself available puts this in doubt.
Williams helped the All Blacks win the World Cup in 2011 but has yet to win with the Kiwis, having lost six and drawn one of his seven Tests so far.
