"It happened to me when I played," Rivera said. "I actually fractured my leg and sprained my anterior cruciate ligament."

"That's a disappointing play. I'm pretty adamant about it," Rivera said. "It really disappoints me. It's a personal thing."
"I know the league is aware of it, mostly because everyone in America saw it."
Johnson suffered the injury on the second play of the third quarter but convinced the coaches to allow him to return to action for the final drive of the game.
"He said, ‘I can give you everything I've got.' And he sure did," Rivera said. "He reached deep down."
