Yankees closer Mariano Rivera will have surgery Friday morning to repair his increasingly raspy voice.

“They have to cut some polyps off the vocal cords,” Rivera said Thursday at a Salvation Army banquet, where he received the organization’s Pinnacle of Achievement award. “We decided to do it as soon as possible.”

The operation will be performed at Columbia-Presbyterian Medical Center, and will leave the 41-year-old speechless for a time.

“A week without talking,” baseball’s all-time saves leader said, “then another week and I’ll be fine. I don’t like surgery, but the doctor said ‘Nothing serious.’”
