Brett Gardner of the New York Yankees will visit Dr. James Andrews on Monday or Tuesday and will then visit specialist Dr. Timothy Kremchek in Cincinnati on Thursday to try to figure out what is wrong with his elbow after he had a setback on Friday.
Gardner, who has been sidelined since April 18 with the elbow problem, could be out until after the All-Star break.
"Obviously something's not right," Yankees general manager Brian Cashman told reporters before Saturday's game. "He still feels stiffness, something's not right. We have to try to figure this thing out because we don't have an answer to it."
Gardner returned to action this week, taking batting practice and beginning a rehab assignment with Class A Charleston.
He went 1-for-3 on Friday night with Charleston, and seemed optimistic he could be back with the Yankees by Monday. But he experienced stiffness and soreness in his elbow Saturday morning.
"He woke up and had pain, so he's going to see the doctor on Monday again," manager Joe Girardi said. "Obviously it's a setback, and I'm not sure when we'll see him now. I said if he had another (setback) my thought would be (we'd see him) after the All-Star break, so there is concern we're not going to have him for a while."
Gardner has played just nine games this season and is hitting .321.
