Whats the craic with the fight tonight?

It's on sky sports 3 from 6pm and then flicks over to sky sports 2 at 8pm, is there fights all the way through or is the first few hours on SS3 just a bull shit build up?

It's alright the Villa are playing on Sky Sports 1 so I am kind of torn between what to watch, a shit football match or a shit boxing card.
