Boxnation had the Diaz and Collazo fights.
Considering Sky and Matchroom will probably want to generate interest in Khan v Kell Brook it wouldn't surprise me to see them pick this up.
His last few fights were on sky werent they?
Think his last one was on BoxNation, as it was the Mayweather undercard. Before that, i'm sure it was mix of Sky and Primetime.
