"Yesterday on my first wave I had a fall," Defay said. "It just went so big, I went straight into the coral with my head, I had four stitches.

"They made me go through the concussion protocols and the results were so-so, so they made me go through them all again this morning. … There’s no trauma, so we’re happy."

Before the Olympics started, American surfer Griffin Colapinto told USA TODAY he’d experimented with wearing a helmet during practice sessions at Teahupo’o. He said thought the equipment would be a common sight when the Games began.
