“I’m feeling okay,” Jonas said. “I’ve been better, but I’m doing alright.”
Jonas said he has a “cracked rib from a spill on a bike and a few other bumps and bruises”.
He added: “I just wanted to go ahead and say that in case I’m not as physically enthusiastic as I usually am.”
Jonas, a chart-topping singer best known for performing with his siblings as the Jonas Brothers, also asked his fellow The Voice coach Blake Shelton to “not make me laugh too much because it hurts to laugh”.
Country music star Shelton joked the injury was an excuse to get sympathy on the show and Jonas replied it was a “big elaborate plan”.
Jonas married actress Priyanka Chopra, 38, in 2018.
