Arkansas has been granted permission to talk to Memphis coach John Calipari about replacing Stan Heath, who was fired Monday. Memphis spokesman Lamar Chance said on Saturday he didn't know whether Arkansas had contacted Calipari yet, but that permission had been granted. Calipari guided Memphis to the NCAA regional final for the second straight season. He received a contract extension through 2012 on Monday. Calipari is 181-63 in seven seasons at Memphis.
