Denver Broncos coach John Fox was released a Charlotte, N.C., hospital Friday morning, the team announced.
Fox was staying at Carolinas HealthCare System's Sanger Heart and Vascular Institute since having heart valve replacement surgery Monday.
"The encouragement I've received from (wife) Robin and my family, friends, the Denver Broncos, fans and so many around the NFL has been incredible," Fox said in a statement. "I am truly thankful for every single thought and prayer that was directed my way.
"My recovery is progressing well -- I am feeling better and getting stronger each day. I will begin the next phase of my recovery in Charlotte and continue outpatient appointments with doctors, who will clear me to return to Denver when the time is right.
"Although I'm eager to return to coaching, my No. 1 focus is my health. I believe in our players and have full confidence in Jack Del Rio and our staff.
Fox also thanked his surgeon, Dr. Mark Stiegel, cardiologist, Dr. Geoff Rose, and doctors Kevin Lobdell and Robert Heyer.
Del Rio, the defensive coordinator, is coaching the Broncos in the interim. Denver travels to San Diego to play the Chargers on Sunday.
Fox was taken to the hospital last Saturday after feeling light-headed at a golf course in Charlotte.
