Thomas played with his father alongside Woods and his son Charlie at the PNC Championship in December, the last time the former world No 1 played before his latest back surgery.
And Thomas led the prayers and hopes of the golf world that Woods makes a full recovery.
“I’m sick to my stomach,” Thomas said. “You know, it hurts to see one of your… now one of my closest friends get in an accident.
“Man, I just hope he’s all right. Just worry for his kids, you know. I’m sure they’re struggling.”
Jack Nicklaus, the only player with more (18) major championships than Woods (15), wrote: “Barbara and I just heard about Tiger’s accident, and like everyone else, we are deeply concerned. We want to offer him our heartfelt support and prayers at this difficult time. Please join us in wishing Tiger a successful surgery and all the best for a full recovery.”
While Justin Rose added: “Just seen the awful news. We know how tough you are, we’ve seen it a hundred times. Hoping and praying you’re ok my friend.”
Ian Poulter said: “Thoughts are with Tiger Woods and others involved. Wishing a speedy recovery and I hope the injuries are not bad.”
American Cameron Champ wrote: “You have to be pulled out with the jaws of life it’s definitely not good circumstances. Hopefully, everything goes well with that and he can make a full recovery.”
