Ricco said Flores should be ready for spring training.
Flores suffered the injury when he was struck by a pitch while playing winter ball for Margarita in his native Venezuela on Nov. 26. The injury was to the bone that sticks out on the inside of the ankle. After a five-day absence, he returned to play for three days before being shut down.
Flores, 24, remains on track to be the Opening Day shortstop for the Mets. He batted .263 with 16 homers and 59 RBIs in 483 at-bats last season.
