My 14 Y.o. Daughter Plays High School Soccer. Planted With

my 14 y.o. daughter plays high school soccer. planted with left foot, twisted and kicked with right foot. scored. only involving herself and ball, went down. Xrays show no break/fx in pelvis. day 2, still cannot bear weight on L side. Tx: ice, rest, lying supine. only up on crutches to bathroom. Pain on outside/lateral hip. What do you think. waiting til monday to go to ortho to see if it reveals itself tear or sprain. any other thoughts?
