Go in the espn app and go to either browse(if on your roku or streaming device) or watch on your phone. Scroll to the channels and find it. It will ask you to confirm thorough your provider.
If you go way down the list to the NCAA Men's Soccer section you can see the link for the Pitt men versus the Louisville men game. It has a little key symbol over by where it says the game is on the ACCNX, which I believe is the symbol that means that the game is locked unless you provide your operator's log in info.
There is also a link there a little further down for the Pitt versus Louisville women's volleyball game.
I guess I should say that there really isn't a link there yet, because the game isn't for three more days. But shortly before the game starts there is a live link in the "Live Now" tab.
