Jim ‘Bones’ Mackay will return to caddieing full-time for Justin Thomas, a representative from Thomas’ management agency confirmed to Golf Digest overnight.

Golf Channel’s Rex Hoggard first reported the news.

“It came out of left field very recently. I have just tremendous respect for [Thomas] as a person and a player,” Mackay told Golf Channel. “It was an incredible phone call to get, and I said yes.”

Mackay has spent the past four years as an on-course analyst for Golf Channel/NBC after spending 20-plus years caddieing for Phil Mickelson. Mackay has caddied sparingly since then for a number of different players including Thomas, who won the 2020 WGC–FedEx St Jude Invitational with Mackay on the bag.

Thomas has had Jimmy Johnson as his full-time caddie since turning professional in 2013, and Johnson worked for him at last week’s Ryder Cup. It is unclear why Johnson will no longer be on Thomas’ bag, although he has struggled with health-related issues in recent years. Once the news broke, Thomas did offer this message on Twitter:

Thomas, 28, is a 14-time PGA Tour winner and the reigning Players champion.
