Annika Sörenstam on the LPGA Tour, Rory McIlroy on the PGA Tour and Phil Mickelson on the Senior Tour were just some of those who paid tribute to Tiger Woods after the serious accident he was in last week.
They played in his classic outfit with a red shirt and black pants.
Woods, who is currently recovering from the surgery required for the fractures he sustained in the accident, is now thanking for the tributes.
"It's hard to explain how touching it was today when I turned on the TV and saw all the red shirts.
To all golfers and all supporters, you really help me through this tough time, "he wrote on Twitter.
It was Tuesday night Swedish time that Tiger Woods crashed his car in California.
He suffered fractures to his right calf and tibia, as well as injuries to his foot and ankle.
