American? I can't stand American commentators, they never know what they're talking about and have a limited vocabulary. It really takes me away from the game...so please tell me some good news?
To answer the OP's question it will be All American commentators. If you don't want to listen to them you can either : 1) Tune into Telemundo 2) Watch a tactical camera angle or another camera angle online on FOX Sports Go that more than likely won't have any commentary at all. 3) Hope there are other language feeds available like When ESPN would have German and Korean available on their digital platforms and Brazilian Portuguese on ESPN Deportes. 4) Mute your television.
Then you are going to have to try and find some bootleg illegal stream that may not be reliable and may give you malware. Or vacation in a country that may have alternate English language options.
