Heath said last week that Sullivan no longer was taking part in workouts, but that he would meet with Sullivan to see if they were "on the same page" for a return.
Apparently, they were not, but Sullivan still is enrolled at the UA and intends to graduate.
"I appreciate his efforts in the past and respect his decision to stay here and continue his education," said Heath in a statement issued through the university.
Sullivan could not be reached for comment.
A 6-foot-8, 239-pounder who signed a letter of intent to play for former coach Nolan Richardson, Sullivan stayed for the transition to Heath after Richardson was fired before the last regular-season game of the 2001-2002 season.
Sullivan played in all 30 games - starting five - during the Razorbacks' 18-12 campaign last season. He averaged 2.3 points, 3.2 rebounds and 0.8 blocked shots per game.
In 84 career appearances - 25 starts - Sullivan averaged 2.0 points and 3.1 rebounds.
