Virginia Tech athletics spokesman Bryan Johnston said Hall was in the water when the injury occurred. Although Hall rode a personal watercraft (jet ski) at the party, he wasn't injured while riding it, Johnston said.
Head Coach Frank Beamer said Hall was not riding a jet ski when he was injured.
Team trainer Mike Goforth said Tuesday that he believed Hall banged his knee while riding a jet ski.
A team spokesman said Hall hurt himself while "just playing in the ocean."
Kansas Athletic Director Lew Perkins issued a statement denying the rumor that Hall, who was wearing a tee shirt featuring a likeness of a Big Mac, was injured while running away from Jayhawk head coach Mark Mangino.
