Nick Saban, but athletic director Mal Moore, the man who hired Saban.
Moore has been hospitalized with heart problems. Moore also was in the hospital last August because of an irregular heartbeat but was released after the tests were negative.
University spokeswoman Debbie Lane said Wednesday that Moore has been admitted to Brookwood Hospital in Birmingham for tests and treatment "regarding pulmonary problems." She said no further information was available on the 73-year-old's status.
Moore has headed the athletic program since 1999 and was the man who hired Saban, arguably the Tide's best coach since Bear Bryant roamed the sidelines. He's also been with the university for more than 50 years dating back to his playing days for Bryant.
