NBC Sports, MRN Extend Partnership On NASCAR Telecasts
The move received mostly positive reviews on Twitter during yesterday’s race. NBC Sports and MRN could additionally look to extend the move to other races this year, as the Xfinity Series has two more road-course races this season. MRN, which is owned by ISC, is one of the two NASCAR radio networks that calls races for affiliates alongside SMI’s PRN. Adam Stern/SBD
