Fans grew concerned for Sanders, 57, when he didn't appear at any of Colorado's football camps over the summer, and then his eldest son, Deion Sanders Jr., confirmed to USA Today that his father was dealing with a pretty significant health issue at the end of June.

Colorado coach Deion Sanders is still "going through" his latest undisclosed health problem and is not yet back with his program. Sanders, entering Year 3 of his tenure at Colorado, has been at his Texas estate since at least June as he deals with his health.
