Asdrubal Cabrera told reporters Sunday he doesn't know if he will be back in time for Opening Day.
"I don't know," the Mets shortstop said. "We've got to wait and see how my knee feels."
Cabrera returned to Florida after visiting doctors Friday in New York, where he received a platelet-rich plasma injection after straining the patellar tendon in his left knee Thursday. Cabrera said he had difficulty walking after the injection, but felt better Sunday.
Cabrer said he initially felt fine on Thursday and was surprised by the diagnosis, which meant two weeks of rest. If he's on schedule, he'll have nine days before the Mets open the season in Kansas City April 3.
"I am just worried to be healthy," Cabrera said. "I want to be healthy and take time, take time, I want to be ready for the Opening Day, of course, but I've got to see how these first two weeks go."
With Cabrera out, the Mets used Wilmer Flores at shortstop Saturday for the first time this spring. He was replaced later in the game by prospect Matt Reynolds, who starts at short Sunday.
