Saturday night's game is being broadcast by FSN Wisconsin, so if you are outside WI, and subscribe to extra sports channels, I'm sure you'll get it.
Friday, will be tougher, maybe non-existant for you. Wisconsin Public Television is carrying the game, but it's a rebroadcast (it's what they always do...retarded I know) at 1030pm. That is carried throughout WI, but you probably won't be able to get it elsewhere, and you'll know the score by then anyway.
So plan on TH for Friday, unless the UW plans to webstream it last minute. Maybe they will if it's a sell out, but as of now, it's not.
