What do you think is up with this situation?

so there's this guy who i really like. he's unbelievably nice, cute, and has great eyes. and i think he might like me too. also, we're both into the same type of sports. we were playing one on one basketball the other day. and i accidentally elbowed him in the face when trying to block the ball. it was a hard hit, right away, i said oh my gosh are you ok!?? he said he was fine, but then for the rest of the night when i was at his house, he didn't really seem to want to talk to me. and he just went and sat down up in his room. i think it might of actually hurt him. i feel so bad. and for the past couple of days, he hasn't answered any of my texts. do you think he's number 1 ok? and number 2 mad at me?? what do i do?
