Terry Francona missed Tuesday night's loss to the San Diego Padres after he was admitted to the Cleveland Clinic for further tests.

Francona, 58, left a game last week after he started to feel lightheaded and his heart rate increased. He dealt with the same symptoms earlier in the season.

Chris Antonetti said that Francona did not experience the symptoms again and that Tuesday's tests are being done to determine what's causing the issue.

"As I've continued to tell Tito, the most important thing is his health and that we focus mostly on that," Antonetti said. "If that means he has to spend a day or two away from the ballpark, then that's what he needs to do."
