Heard, a sophomore last year for the Cornhuskers, will sit out the fall of 2013 and have two seasons of eligibility remaining for the Wildcats. He also considered transferring to Pittsburgh.
The 5-foot-11, 185-pounder rushed for 348 yards and three touchdowns for Nebraska in 2012, averaging 6.7 yards per carry. However, he was third on the tailback depth chart behind 1,000-yard sophomore Ameer Abdullah and veteran Rex Burkhead.
Getting the former four-star recruit to come to Kentucky is a big coup for new coach Mark Stoops who, incidentally, went to the same high school as Heard -- Cardinal Mooney High in Youngstown, Ohio.
