Ouch man, sorry to hear about that. Hopefully it's just a sprain and not a tear. As much as you want to keep going and compete I hope you don't do so if you tore something. Risking a greater injury which puts you out for a far longer time (partial tear turning into full tear) or possibly not regaining full mobility is something to really take seriously. You may have missed the moment to respect that leg lock but you still have time to respect the injury if it's serious. :)

Hopefully it's not and you heal well enough to compete!
