The New York Yankees will be without manager Aaron Boone for the foreseeable future.

The team announced Wednesday Boone is taking an “immediate medical leave of absence” for pacemaker surgery, which is expected to take place at St. Joseph's Hospital in Tampa.

Boone and Yankees managing partner Hal Steinbrenner both issued statements, with the Yankees skipper explaining he has experienced mild symptoms of lightheadedness and shortness of breath in recent weeks.

Doctors recommended a pacemaker given Boone's low heart rate. He said medical professionals believe the surgery will allow him to function more normally:

“[The doctors] are confident that today's surgery will allow me to resume all of my usual professional and personal activities and afford me a positive long-term health prognosis without having to change anything about my way of life,” Boone said, via ESPN's Marly Rivera. “I look forward to getting back to work in the next several days, but during my short-term absence, I have complete trust that our coaches, staff and players will continue their training and preparation at the same level as we've had and without any interruption.”

Boone had undergone open-heart surgery as a player for the Houston Astros back in March 2009. He played in 10 games with the Astros that season, but called it a career shortly thereafter.

The 47-year-old is in his fourth season as manager for the Yankees. Boone finished second in the American League Manager of the Year voting in 2019, leading New York to the ALCS. The Yankees were ousted by the American League champion Tampa Bay Rays this past season, but are regarded as a top contender in 2021.

Luckily, Aaron Boone and the medical professionals are optimistic about the procedure. He should be able to return to the bench in short order. For now, Yankees players and staff  can only send their well-wishes.
