the owners of the local NBC affiliate stations have not agreed with the contract with DirecTV. As a result and at the moment NBC is not available on DirecTv in those areas/cities.
In case this is not resolved by Saturday there are two options both free to watch the ND game. Stream it from either NBCSports or from Locast. The last option is via the Apps (Menu) on your DirecTV. Click on Menu then scroll right to get to "Launch TV Apps”. Wait for it to load and then click on Locast. You also have to go to their website (locast.org) on your computer/phone to activate. I tried them both and preferred the NBC Sports option.
