Indians manager Terry Francona is undergoing more follow-up tests at the Cleveland Clinic.
He will miss Tuesday's game against the San Diego Padres.
Francona was hospitalized June 13 following a game at Progressive Field.
The 58-year-old manager left the game on June 26 because he wasn't feeling well. The Indians say he underwent tests at Cleveland Clinic and doctors, for now, have ruled out major health issues. He will be monitored the next several weeks.
Brad Mills, bench coach for the Indians, will fill in for Tuesday's game.
The game is at Progressive Field and it starts at 7:10 p.m.
