DENTON, Texas (AP) – North Texas football coach Dan McCarney says he had a stroke but expects a full recovery.  McCarney told The Des Moines Register that he felt his left side go numb after a workout Sunday morning. Doctors later confirmed he had a stroke.  McCarney continues to undergo tests, but says he’s told he won’t have any permanent damage and should be out of the hospital in a few days. He calls himself a “pretty lucky guy.”  The 58-year-old McCarney became coach at North Texas in November 2010. He was the coach at Iowa State from 1995 to 2006 and an assistant at Florida, South Florida, Wisconsin and Iowa.  The UNT athletic department declined to comment.
