I've noticed that for this Friday BoxNation is currently showing as "No Information" on the Virgin EPG between the hours of 8pm and 11pm. On SKY however it shows as "Live- World Title Boxing". I've checked the BoxNation website but there is nothing listed for this Friday.
The only show that I can see that might be broadcast live this Friday is an event from Kazakhstan that is jointly being promoted by Ricky Hatton. It's not exactly "World Title Boxing" but it is live action.
Here's more info for anyone interested:
