Can anyone tell me likely sports injury i might have?

i was in my mixed martial arts class and sparring with another class member. we were working on kickboxing. i got kicked full force right above my knee on the side of my thigh. it has been roughly 4 hours after class and i still have major pain. there was no popping or cracking on the initial contact. right now it hurts to bend this leg even sitting down. i can extend it fully though(i have pain when doing this). it is also really ******* tensed up, the best way to describe it is that someone put a rock in the side of my thigh.
