Moore was admitted to DCH Regional Medical Center on Tuesday evening because of an irregular heartbeat.
"Coach Moore is doing fine," said Dr. James B. Robinson, his personal physician. "He is undergoing a series of tests today and all the results are coming back normal. I anticipate that he will be discharged soon."
