Mariano Rivera said Wednesday that when his agent referred to "complications" during an exam of his injured knee, he was speaking in regards to a blood clot in Rivera's right calf. "I'm OK," Rivera said. Rivera tore the anterior cruciate ligament and damaged the meniscus in his right knee last Thursday at Kansas City when he stumbled and fell while shagging a fly ball during batting practice. He likely will miss the rest of the season. Rivera also revealed Wednesday that his plan all along was to come back and play next year.
