No regular boxing to date but they do show classics occasionally. There was a two week period a couple of months back where they had an hour and a half long show every night at 7 (or there abouts) showing a different match up. They seem to show quite a bit of Mike Tyson too.
First of all, its FNF-Friday Night fights, not FFN-thats Sky's Friday Fight Night. T'aint rocket science But don't expect FNF to be shown live for the first few weeks. ESPN signed a contract to show the NBA over here, and at the moment the only two games a week they have are Wednesday at midnight and Friday nights at 1am, which rules out FNF being live at least until the Basketball is over. And NO, they won't bump the NBA for FNF, ESPN have been fairly smart in only purchasing NBA rights for the games ESPN show in the states as well, so it hasn't got Fox, TNT or some other logo stuffed all over the page. And those games are a wednesday and friday night. Presumably they will show it on delay on the saturday afternoon, like they did this time out which is fine really, you won't have to stop up all night to watch it. And they may show FNF live after the Basketball's finished (April is the end of the regular season, the play-offs are done by the end of June) but that is quite a while away.
