MIAMI - Michael Cuddyer went to manager Terry Collins Friday and told him he couldn't close his right hand because of a sore wrist. That was enough for Collins to keep Cuddyer out of the lineup Friday night and for the Mets to send him to see a doctor.

The Mets said Cuddyer has tendinitis and will be in a splint for a few days.

The Mets also were without Daniel Murphy, who had a platelet-rich plasma (PRP) treatment for his sore left quadriceps and is out at least until Sunday.

With Wilmer Flores expected to arrive at Marlins Park during the game after visiting his ailing grandfather in Venezuela, Collins went with Kelly Johnson at first base and Juan Uribe at second. Rookie Michael Conforto was the cleanup hitter.

Cuddyer said the wrist has been bothering him for about a week. He saw a doctor and was given anti-inflammatory medication two days ago, but the injury has gotten worse. "It was worse [Thursday], which was worse than the day before that," Cuddyer said. "Grip and range of motion is slim to none. Hopefully it's nothing big and the doctor can diagnose it. I don't know what it is."

Murphy, who left Wednesday's game after three innings and had the treatment Thursday, said he isn't sure when he will be able to return. "It may take a day or two to take effect," he said. "That's what the doctor told me. It doesn't feel terrible, so I'm encouraged."

Murphy missed a month earlier this season with a quadriceps injury. He said it doesn't feel as serious this time.
