I popped a hamstring in a club championship golf tournament a few years ago. Heard a pop and it felt like a ball hit the back of my leg. I got up and tried to take a step forward and went down. Two putted the hole for par but could not really swing great on the next tee. I had to drop out and go to urgent care. They put me in a boot. It didn’t take all that long to heal maybe a few weeks? The worst part was that I was leading my flight on the second day of the tournament and had to withdraw.
