Mariano Rivera was carted off the field in the middle of Yankees batting practice with his right knee propped up.
Rivera injured the knee while chasing fly balls in batting practice. At 6:10 local time here, he was running back toward the fence, reached out to grab the ball and then spilled onto the warning track. He began writhing in pain almost immediately. The team sent him for an MRI after being examined by the Yankees training staff and Kansas City associate team physician Dr. Joe Noland.
The preliminary diagnosis is a twisted right knee. He is currently at Kansas City Med West hospital receiving an MRI.
He was smiling as a John Deer groundskeeper's cart pulled off the field and was brought into the clubhouse on the shoulders of manager Joe Girardi.
