Cleveland Indians manager Terry Francona will not manage the American League in Tuesday's All-Star Game after he underwent a heart procedure to address an arrhythmia on Thursday, the club announced.
Francona is expected to be discharged sometime this weekend after the catheter ablation conducted at the Cleveland Clinic.
The Indians said in a statement that they expect to have Francona, 58, back managing the team when the second half begins July 14.
Bench coach Brad Mills is filling in with the Indians while Francona is away. Mills, who managed the Houston Astros for three seasons, is Francona's closest friend. They played together at Arizona and Mills was on Francona's staff in Philadelphia and Boston before coming with him to Cleveland five years ago.
Francona named his entire major league coaching staff to the AL All-Star coaching staff, and also added Tampa Bay Rays manager Kevin Cash. It's expected Mills will manage the AL team Tuesday.
Francona's health has been an issue for nearly a month, and he has missed games in past seasons due to health concerns. The defending AL champion Indians enter Friday's play 45-39 and leading the AL Central.
Before Thursday's series finale against the San Diego Padres, outfielder Lonnie Chisenhall said Francona's absence is noticeable around Cleveland's clubhouse.
"He interacts with the guys so much," he said. "It is a little different. It's a little quieter. There's a lot less cards to be played and things like that. That means a lot to guys, having that routine and being able to communicate with your manager. We're missing that."
