After an absolutely awesome ending to the Mid Season Finale main event deathmatch showing early this morning (UK time), it has been announced on the official Lucha Underground twitter page @LuchaElRey that the second half of season 3 resumes in the 'Summer 2017'.
I guess it's to avoid going against WWE's Road to WrestleMania. But anyways I hope some TV channel like Challenge snaps up the rights to broadcast this epic show in the UK.
Edit - Resumes on June 1st (GMT) with the "All Night Long" LU Championship match (not saying who's champion or number one contender because spoilers). For those unfamiliar with the stipulation, the match lasts through the whole episode time, and the wrestler with the most pinfalls and submissions wins the match. Being a LU Championship match it is obviously "No DQ anything goes", and the last one in season 1 between Prince Puma and Johnny Mundo (John Morrison) was EPIC.
