The ISM Connect 300 is happening on Sunday. The green flag drops at 2pm.
It's part of the  Energy NASCAR Cup Series.

The race will again serve as the second race in the playoffs, where it functions as a stepping stone for aspiring champions.  It will feature 16 championship hopefuls in the full 40-car field.

As usual there's lots going on this weekend at the track.

In addition to Sunday's Monster Energy NASCAR Cup Series race, the Camping World Truck Series, Whelen Modified Tour, and American-Canadian Tour will run a tripleheader on Saturday, Sept. 23.
