76ers head coach Doug Collins has been suffering from headaches and dizziness since a fall in a coffee shop on Memorial Day.

He sustained a concussion in the fall.

Collins flew out early Tuesday afternoon and had a neurological appointment at Lankenau Hospital.

"He told us this morning, he hadn't said anything before," said assistant coach Michael Curry.

"Hopefully they'll run the tests and hopefully he'll be good. I haven't noticed any difference. We've been meeting a lot and going over a lot of things in preparation for these next two games and for the start of the season. We've been together a lot and spent a lot of hours together. I haven't seen anything different."
