"I'm very glad that the organisers have come around to that way of thinking."
McCullum was philosophical about the dramatic turn of events.
"When I signed up for my season of rugby I didn't think it would have an impact on my cricket eligibility," he said. "But I guess that's why Ted is one of the best.
"I've played a lot of cricket with Flem and the Team Cricket guys. But I haven't played on the same team as Richie McCaw and Kieran Read, so this is actually quite a cool opportunity.
"And I'm looking forward to seeing what plans Flem and the boys have for me. I want to do well for whoever I play for so I'm really up for this challenge."
"We've been told that this decision is final. I'm sure Flem will find a suitable replacement.
Fleming said he was disappointed a loop hole in the rules had allowed his captain to be "poached" by Team Rugby – but confirmed he had already found the perfect replacement.
"We've recruited Nathan McCullum to take Brendon's place," Fleming said. "It was the only sensible move – and not just because at this late stage we've already got a team shirt with "McCullum" on the back!
"Nathan is a quality player who won matches for New Zealand with the bat and ball, so it's not like our side is any weaker."
Nathan McCullum said he was delighted to be called up to play in the match – and was looking forward to dismissing his brother.
"We've played against each other a few times over the years and it is always fun," Nathan said.
"But I don't really know how Brendon considers himself to be a rugby player – I reckon he is just star-struck," Nathan said.
To accommodate the switch – and placate Team Cricket - match officials granted Team Cricket the right to select a player from the Team Rugby line-up as compensation.
Team Cricket player-coach Stephen Fleming selected All Blacks halfback Aaron Smith, who now fills the wildcard spot in his line-up.
"I've heard through the grapevine that Aaron has been [Team Rugby captain] Kieran Read's main training partner and has been smashing it in the nets," Fleming said.
"So there's a bit of payback there in nicking Kieran's mate – but Aaron is also exactly the type of player we are after."
Smith confirmed he was looking forward to the chance to get one over some of his rugby mates.
"I was a bit surprised when I received the news that Flem had claimed me," Smith said.
"But it's actually pretty cool. I get the chance to play alongside some of the greats of New Zealand cricket and go head to head with some of my rugby mates. That's awesome."
Brendon McCullum's shock switch – along with Team Rugby's recruitment of Australian global T20 superstar David Hussey – levels an already intriguing contest even further.
As well as two experienced professionals, Team Rugby also boasts former Central Districts U19 opening bowler Jordie Barrett, New Zealand's U19 world cup captain Kaylum Boshier and former first class cricketer Jason Spice.
Team Rugby captain Read played senior club cricket at the age of 13 and captained Northern Districts at U19 level before deciding to concentrate on rugby, while Israel Dagg was a noted fast bowler as a schoolboy.
Team Cricket, however, boasts recent international stars such as 2015 world cup hero Grant Elliott, recently retired Black Caps wicket keeper Luke Ronchi, test cricket hat trick taker James Franklin and veteran batsman Hamish Marshall.
"It certainly is shaping up as an intriguing contest," Fleming said.
"Brendon's decision to jump ship has given it an extra bit of spice for sure. I can't imagine our bowlers are going to be thrilled with this news."
