Update by Mike (7:49pm): They’re calling it a “twisted right knee” at the moment and Rivera is headed for an MRI. He was examined by the training staff and the Royals’ team doctor.
7:19pm: According to multiple reports out of Kansas City, Mariano Rivera was taken off the field during batting practice this evening after he apparently hurt his right knee while shagging balls in the outfield. According to MLB’s Whitney Holtzman, Rivera was “writing in pain, holding his knee” after going down. Royals’ broadcaster Nate Bukaty says Yankee players believe Rivera slipped on the warning track while others say he “stumbled or hit the wall.”
Either way, he was carted off the field with assistance from Joe Girardi and the team medical staff. David Waldstein reported that the Yanks’ closer was in obvious pain, and he is putting no weight on his right leg. As of 7:30, the YES Network is on the air covering this story.
Clearly, this is not a good development, but we have no prognosis now. We’ll have word from the team as soon as they release anything. If 2012 truly is Rivera’s last season, this is not a good way for him to go out.
