I don't join the match

I was finding normal draft match. We all ban champions, select our champions. when we were loading, I have seen I am 100% loaded. we all were except one. I had this screen for very long time. When the game finally started I have seen that the game went for a time, we were about to surrender and they wanted to report me. Also, there was a message on the screen that said something about AFK so I decided, they seen me like AFK player. Probably I will get some reports for this bug. In my 2 others match that I played just after this one enemy team had problem with AFK player. I think there was the same problem. If there are some grammar mistakes I'm sorry for it.
