Harris, 6-0, 180 pounds, was teammates with Arkansas freshman running back A'Montae Spivey last year when they led the Red Devils to a 14-0 record and the Class 7A state title.
Harris is expected to depart Fayetteville today after arriving early Friday for an official visit.
"He's a real physical guy," Central Coach Jamey DuBose said of Harris. "He has tremendous speed."
Harris showed off his speed at two summer camps.
"I know at Alabama and LSU, he was clocked in the 4.3s in the 40," DuBose said.
He announced a top seven of Arkansas, Tennessee, LSU, Mississippi State, Alabama, Ole Miss and Central Florida in July.
