I may be wrong but I'm 99% sure there is no streaming of CBS Sports games. In my experience the only time they stream these games is if a game before one runs over. They will then put a stream up of the 2nd game until the previous game ends. I also checked on the
Umass and UD sites and there is no link to a stream for tonights game.
So if you want to watch the game tonight you will need to find a TV with CBS Sports or find a link to one of the bootleg streams.
