yeah every tuesday and occasionally fridays, last couple of months they've had froch v taylor, froch v pascal, mtagwa v lopez, carson jones v tyrone brunson, allan green v tarvis simms
Plus Eurosport have a live fight this upcoming friday at 8pm. They're usually garbage, but it's not really their fault. Interestingly, the Yuriokis Gamboa v Jonathan Barros world title fight later this month is an Arena-Box card, and they tend to show either Arena-Box or K2 shows. Hopefully that'll get shown.
That's pretty much it for boxing on sky. Obviously there's the usual stuff on Sky Sports. ESPN tend to show their Friday Night Fights delayed sometime over the weekend if you have that channel. That's about it for regular stuff though.
KOTV-is on every tuesday night/wednesday morning in the early hours on channel 4, next one is on the 10th at 2.35am, think you can watch all the past episodes on 4 on demand. Shows some delayed highlights of bigish fights and some good domestic stuff from thailand.
