Mariano Rivera may have torn ACL
Yankees closer Mariano Rivera was carted off the field Thursday night in Kansas City after apparently suffering a right knee injury while shagging fly balls during batting practice. The team announced a preliminary diagnosis as a twisted right knee, but an MRI taken during the game revealed that he may have suffered a torn ACL, according to manager Joe Girardi. Rivera will return to New York with the team to be re-evaluated to confirm the extent of the injury.
It was shortly after 7 p.m. Eastern Time when Rivera's knee buckled when he reached for a fly ball near the warning track. He was helped on a flatbed truck and driven away with head athletic trainer Steve Donohue at his side. Rivera had to be helped into the clubhouse unable to put pressure on the leg.
Rivera routinely shags fly balls prior to Yankees games, so the activity was not out of the ordinary for the veteran reliever. If a trip to the disabled list proved necessary, it would be his first visit since a groin injury in 2003.
