No danger will it be on an undercard, think the Sauerlands know the biggest chance of a huge crowd is to have over here, Prograis would make too much of a fuss if it was in Glasgow and London is probably too far for a Scottish contingent to travel so Manchester makes sense.
I would image that if Sky take up the option to show it that we could see a few Matchroom fighters on the bill to try and get a bigger crowd or they may even double up on finals, who knows
Just what I've been told from someone who is pals with JT
