What are some good excuses to leave basketball practice with a friend?

Okay so my basketball team has practice from 6-8 p.m. and me and my friend were gunna have a sleepover that nite. I need a good excuse to leave practice 30-35 minutes early. And also he offers to pick anybody up or drop them off if they need a ride. i was thinking of saying i dont have a ride so they are going to take me but he always offers a ride. My coach is super strict and like really into basketball and stuff with all the plays and stuff so i am worried on what i am going to say. we are leaveing early cuz she has a softball game at 8 so shes gotta be there early. idk if i left out any important information but please!! try to help me!! ASAP
