Davis flew back to Florida on Wednesday and is due back at the team's Spring Training complex by Thursday morning. He will not be limited in his activities going forward.
"It was a continuation of his physical," manager Terry Collins said. "When we get the final reports from the doctors, we'll know what it is."
In a text message, Davis described the examination as "just more yearly physical things," though he did not reveal the exact nature of the issue.
Davis, who has been working out in Port St. Lucie for over a week, batted .302 with seven home runs prior to suffering a bone bruise in his ankle last May.
