The former New Zealand captain had retired from all forms of international cricket in 2016 but continued to ply his trade in various T20 leagues across the globe.
Former New Zealand captain Brendon McCullum announced his retirement from all forms of competitive cricket after the conclusion of the ongoing Global T20 Canada terming his journey as "one hell of a ride".
McCullum, who is playing for Toronto Nationals, had retired from all forms of international cricket in 2016 but continued to ply his trade in various T20 leagues across the globe.
The 37-year-old former Kiwi skipper has played 101 Tests in which he scored 6453 runs with 12 hundreds and highest score of 302.
In 260 ODIs, he scored 6083 runs with five hundreds while 71 T20 Internationals fetched him 2140 runs.
However, he has a staggering T20 career (all leagues included) as he scored 9922 runs from 370 games so far.
"It is with pride and satisfaction that I am today announcing my retirement from all cricket following the conclusion of the GT20 Canada. I now won't be playing in the Euro T20 Slam and I sincerely thank the organisers for their support and understanding of my decision," McCullum said.
"As much as I am proud of what I have achieved in my 20-year professional career -- more than I ever could have dreamt of when I first entered the game -- I felt the drive to keep going, harder to maintain in recent months," said McCullum, who was one of the commentators during last month's ICC World Cup.
No one can ever forget McCullum's magnificent 158 not out off 73 balls for Kolkata Knight Riders against Royal Challengers Bangalore in the opening game of the first edition of the Indian Premier League -- an innings that was instrumental in the league gaining instant popularity.
"My style of cricket has always been full noise and full throttle. From Culling Park to Lord's and everything in between, there has been some wonderful memories. Unfortunately, the sacrifices needed and commitment required to play that type of cricket have now become too great. I owe it to myself and the teams I represent to close that chapter rather than plough on regardless of what I know to be true," McCullum further added.
The dasher from Canterbury is extremely proud for the manner in which he played the game.
He was trailblazer in his own right and is happy that the Kiwis broke boundaries during his tenure in international cricket.
"With New Zealand, we broke boundaries and established a style of play that earned us respect across the world. In T20 cricket, I have enjoyed so many varied challenges, I can leave the game knowing I left no stone unturned."
