Rivera is expected to get a second opinion, but said he would stay with the team in Kansas City and won't go back to New York immediately. The Yankees return home Sunday after finishing the four-game series with the Royals.
"At this point, I don't know," Rivera said when asked if he would pitch again. "We'll have to face this first. ... It depends on how the rehab will happen and from there we'll see."
Rivera injured his right knee during batting practice before Thursday's game at Kauffman Stadium. Rivera was examined by Royals doctor Joe Noland and Yankees trainers before being sent to KU MedWest for an MRI.
Girardi and bullpen coach Mike Harkey picked Rivera up off the ground and carried Rivera to a cart to be taken off the field.
YES Network had video footage of Rivera shagging fly balls that showed a ball hit by Jayson Nix that went over Rivera's head and he jumped to try to catch it, but it appeared his right knee buckled and he fell to the ground.
They also showed the reaction of Nix and Alex Rodriguez. Rodriguez, who was behind the batting cage could be seen saying, "Oh, my God. Oh, my God."
Here's the video:
MLB Network showed live footage of Rivera being taken off the field. Rivera was slumped against the center-field fence during Yankees batting practice before Girardi and Harkey helped him to the cart.
Rivera has shagged foul balls throughout his career in the big leagues. Considered one of the team's best athletes, Rivera has often joked that he'd like to come back as a centerfielder after retiring as a pitcher.
"If it was going to happen, it happended doing something I love to do," Rivera said, "and shagging is something I love to do. If I had to do it over, I would do it. No hesitation."
