Denver Broncos coach John Fox gave everyone quite a scare on Saturday when he was taken to the hospital after becoming dizzy and feeling chest pains.  It was suspected that he had a heart attack.  While that wasn’t the diagnosis he needs heart surgery and will miss several weeks, team spokesman Patrick Smyth confirmed Saturday night.  The 58-year-old Fox will undergo aortic valve replacement surgery early this week at a hospital in Charlotte, N.C.
