How to turn off the spoilers for LCS matches?

Just wondering how to turn off the spoilers on matches, I know they use to have an option but it doesnt seem to be there anymore. It is so anoying since I can't watch the games live and like to watch them at a better time for me. Although i can't now because i just get shown who wins and wrecks the whole game. I have to try and do this stupid thing where I cover my eyes and hope to god i click a game I would want to watch and somehow find the play button without seeing who wins.
