Knowing all too well what it's like to be struck down by injury, Tiger Woods spared a thought for Kevin Durant on Tuesday, after watching the Golden State Warriors forward crumple to the floor during a game against the Toronto Raptors.

"It was sad," said Woods, during his U.S. Open pre-tournament media conference. "As athletes we've all been there, to that spot when you just know it, that something just went, and can't move, can't do much of anything.

"You can see it on his face. You just know."
