The world number one golfer is set to celebrate another year in his 20s in style.
The world number one golfer might be marking his 26th birthday in Las Vegas - but it's unlikely to be a night filled with all night partying.
The Co Down native is reportedly flying via private jet from San Francisco to Sin City to sit ringside for Floyd Mayweather and Manny Pacquiao's much hyped boxing match on Saturday night, according to the Irish Daily Mail.
But he will be competing at the WGC Cadillac match Play Championship in California that weekend and if he makes it past the quarter finals, he will have to fly straight back to The Golden State to compete at 9am the next morning.
McIlroy still has another day to mark the occasion as he celebrates his birthday on Monday, May 4th.
There's no word on whether or not he will be joined by his girlfriend, PGA employee Erica Stoll.
The pair rang in the New Year together in Dublin and Mayo and have managed to avoid being photographed in their seven month romance.
