ACL tear

hey guys so I fell on September 9th really hard on my knee without knee pads, my knee twisted and I heard a pop I walked it off and played anyways. I went the the trainer and he wanted me to get pictures over the weekend to make sure it was okay. I came back Monday saying it was okay because I wanted to play again. he made me over do it and I ended up in the er. they sent me for an MRI and an orthopedic apt and the dr seemed REALLY concerned but wouldn't really tell me anything. should I be anticipating a bad result from the MRI?
