🥊🔥 THE TURF WAR CONTINUES! THE BATTLE OF THE STADIUMS! 🔥🥊
79 YEARS IN THE TURF INDUSTRY. TWO GROUNDSMEN. ONE BOXING RING. AND ABSOLUTELY NOWHERE TO HIDE!🥊
Earlier this week, we travelled to Auckland to catch up with Mark Perham at Go Media Stadium.
Now it's Waikato's turn to have their say! 🔴🟡⚫
We caught up with Karl "KJ" Johnson at FMG Stadium Waikato, the home of the Gallagher Chiefs and Waikato Rugby, to hear his side of the story ahead of what promises to be one of the most entertaining showdowns at RUMBLE ON THE RIVER!
And if there's one man who knows every blade of grass at FMG Stadium Waikato, it's KJ!
For decades, he's been one of the unsung heroes behind some of the biggest sporting occasions in our region. From Super Rugby clashes to international rugby fixtures, KJ has dedicated his working life to preparing a world-class sporting stage.
But on Saturday 28 November, the man who normally prepares the battlefield is about to become a warrior himself!
🏟️ KARL "KJ" JOHNSON – FMG Stadium Waikato
🆚
🏟️ MARK PERHAM – Go Media Stadium
WAIKATO vs AUCKLAND!
GROUNDSMAN vs GROUNDSMAN!
THE ULTIMATE TURF WAR! 🌱🥊
Between these two gentlemen, there's an incredible 79 years of experience in the turf industry. That's a fair few kilometres behind a mower, a mountain of grass clippings and thousands of hours preparing sporting surfaces for some of New Zealand's greatest athletes!
But there's one thing neither man has spent much time preparing for...
GETTING PUNCHED IN THE FACE! 😂🥊
At 55 years young, KJ has openly admitted that stepping into a boxing ring is well outside his comfort zone. But that's exactly what makes this contest so special.
Two highly respected gentlemen, two sporting stadiums, two proud regions and one very worthy cause.
💙 MOVEMBER – MEN'S HEALTH & MENTAL HEALTH AWARENESS.
Too many good men struggle in silence, and KJ's willingness to put himself on the line is a tremendous example of stepping outside your comfort zone, challenging yourself and doing something meaningful for others.
And while there will undoubtedly be plenty of friendly rivalry, banter and perhaps a little sledging between Waikato and Auckland, there's enormous respect between these two men.
But once that bell rings, all friendships are temporarily on hold! 🔔🥊
🎥 WATCH OUR EXCLUSIVE INTERVIEW WITH KARL "KJ" JOHNSON FROM THE MIDDLE OF FMG STADIUM WAIKATO!
We hear how the training is going, his thoughts on his Auckland opponent and why he's decided to trade his trusty lawnmower for a pair of boxing gloves!
This is shaping up to be an absolute cracker and quite possibly WORTH THE PRICE OF ADMISSION ALONE!
