Is it alright for him to watch UFC now?

[HappyTeenageMom]

My son is only a year old and already he watches UFC. Now don't get me wrong I like it but I never let him watched it (not till he got a bit more older that is). It's just one day I turn my tv on and he saw it when I changed the channel he got upset and started crying so when I went back he got happy and clapped his hands. Now whenever I go to my boyfriends house (he usually has UFC on) my son goes for that and sits there and watches it. I mean yeah the sport is great but im not sure if it's suitable for him yet.
