In Game Champ select Bug

While I was waiting in the Queue, I accepted a game. I then got stuck in the Queue, with nothing to do for 30 seconds. Then, I entered a Game saying there was 84 seconds left to champion select, so I ask to my team what lanes were left. They told me ADC. So I was about to pick Ezreal and I got kicked saying I didn't chose a champion in time. It's not a major problem and I only got a 5 minutes to wait after, not a big deal but I prefered sharing the information.
