A friend of mine brought this up awhile ago and said something similar happened last nite.
Play 1 - Girl dives on floor for ball and slides to a stop near the sideline. Her ponytail, following the laws of Thermodynamics, continues to 'head' to the sideline. She is about 4" inbounds, however, the pony tail comes to rest out of bounds. He blows the whistle for OB
Play 2 - A1 B1 scramble under basket for loose ball. A1 is partially sitting and B1 is reaching for the ball. As A1 leans on her elbow, her ponytail is touching OB. Both players now have a firm grasp on the ball. In this case it was called a JUMP and went to AP
From what I understand, in BOTH cases the players were wearing legally approved hair control devices
