Memphis' coach, Penny Hardaway, is alleged to have assisted Wiseman and his family move to Memphis past year.
Wiseman will be allowed to play in Memphis' game Friday night after a court-issued "emergency temporary restraining order" was put into effect less than one hour before tip-off, according to a statement released by Memphis.
Wiseman scored 28 points and pulled down 11 rebounds in his first - and perhaps only - game for Memphis. Wiseman was a standout junior, helping Hardaway win his third straight Tennessee Class AAA title before being hired by Memphis as head coach at his alma mater in March 2018.
Ballin said he has filed a lawsuit against the NCAA and the U of M on behalf of Wiseman.
"The University is now working with the NCAA staff to restore his playing status, and we are hopeful for a speedy resolution to the matter", said a statement released by the school.
Though the two have a long-standing kinship, Ballin says the NCAA deemed Hardaway a booster, leading to the ruling of Wiseman's ineligibility.
ESPN's Adrian Wojnarowski initially reported that the NCAA had ruled Wiseman ineligible to play. He also coached him at East High School in Memphis en route to a state championship.
This is a major blow to both Memphis and Wiseman.
"The University of Memphis is enjoying a tremendous period of positive momentum and success on multiple fronts including the excitement surrounding our men's basketball program", stated Laird Veatch, University of Memphis Director of Athletics.
