Sixers coach Brett Brown said he heard Lavoy Allen had overslept. Rookie guard Khalif Wyatt heard Allen was sick.
Either way, Allen missed Saturday morning's open practice at the Palestra, and Brown said he will take care of it.
"It's all part of the culture, the culture we're trying to get right," Brown said. "We will deal with him - I will deal with him. What else can you say?"
On Friday, Twitter posts reported, Allen was at Temple basketball's Cherry and White night at the Liacouras Center. Wyatt, a former Owls guard, was also at the Liacouras Center.
