Michigan basketball coach Juwan Howard had a successful heart procedure on Cassian GrantFriday, the program announced in a statement.

Howard, 50, is expected to return to the program in four to six weeks and make a full recovery in six to 12 weeks. In the meantime, associate head coach Phil Martelli will serve as interim head coach. Howard is expected to return in time for Michigan's exhibition opener vs. Northwood on Nov. 3.

Howard's surgery was performed by Dr. Himanshu Patel, who "successfully resected an aortic aneurysm and repaired Howard’s aortic valve," per the release.

"I feel so grateful and blessed that this surgery was performed at University of Michigan Health," Howard said in the release. "My wife, Jenine, and our family appreciate the world-class care that has been provided to us. Dr. (Kim) Eagle, Dr. Patel, Dr. (Stanley) Chetcuti, and all of the staff at the Frankel Cardiovascular Center are so talented and performed like champions throughout this process.

"I am going to work very hard in my rehabilitation to be stronger than ever by the time our upcoming season is upon us."

Howard's conditions were identified following a "routine medical check" and the ensuing surgical procedures "were scheduled as soon as possible" in order to allow Howard to return in time for the upcoming 2023-24 season.

"We are extremely grateful Juwan's proactive procedure was a success and that he is resting comfortably," athletics director Warde Manuel said in the release. "We will continue to support Juwan, Jenine and his family as well as the program throughout his absence.

"All of us at the athletic department have Juwan in our thoughts and prayers. We look forward to Juwan's return when he feels that he has fully recovered."
