Not an athlete, but fits the bill.
https://www.si.com/golf/news/caddie-rushed-to-hospital-after-collapsing-at-pebble-beach"PEBBLE BEACH, Calif. A caddie for amateur Geoff Couch, a local businessman, collapsed in the 11th fairway at the AT&T Pebble Beach Pro-Am at Pebble Beach Golf Links in Friday's second round.
The caddie, whose name has been withheld, was given CPR first by an unidentified spectator who was on the rope line. An officer from Cal Fire then took over the life-saving procedure. The caddie was eventually removed by ambulance, which took some time because the 11th is not an easy entry or exit point on the golf course. Eventually the caddie was taken to Montage Health in Monterey.
"With my perspective, it seemed like we'd lost him," said Lukas Nelson, a CEO and the second amateur in the group, who was the only one of the three remain participants willing to speak. "I turned around, he's on the ground and ran over to him and turned him over and he didn't have a lot of color."
If you think I am a liberal, you are incorrect. Assume sarcasm on my part. Sorry if something I post has already been posted. Just the way it is!!
