Justin Thomas has announced he is splitting with caddie Jim 'Bones' McKay just a week before the Masters Tournament gets underway at Augusta National.

The legendary looper started working with Thomas in late 2021 and was on the American’s bag when he won his second PGA Championship title in 2022.

Before linking up with the two-time Major champion, McKay had previously been the bagman for Phil Mickelson for 25 years, caddying him for all but one of his six Major Championship victories, including his three Masters Tournament triumphs in 2004, 2006 and 2010.

In his two outings with McKay on the bag at Augusta National, Thomas finished in a share of eighth in 2022 before missing the cut last year.

It is not currently known who will caddie for the 15-time PGA Tour winner at the first Major Championship of the year.

"While incredibly difficult for me to say, Bones and I have parted ways,” said Thomas on social media.

"I'm going to be forever thankful for him joining me on the bag in 2021.

"The things we've been able to accomplish together - the PGA Championship in 2022, the Presidents Cup, the Ryder Cups were all unforgettable experiences.

"His wisdom on and off the course has been a blessing during a tough stretch of my career and he was there every step of the way.

"I know there are great things coming for both of us down the road. I wish him the best of luck and will always count him and his family amongst my friends."
