DARLINGTON, S.C. — NASCAR has postponed all track activity Friday and canceled qualifying for its Sprint Cup and Xfinity races at Darlington Raceway in anticipation of Hermine bringing inclement weather to the South Carolina track.

Hermine strengthened into a hurricane Thursday.

Both the Sprint Cup Series and the Xfinity Series had scheduled practices Friday and were supposed to qualify Saturday. However, in the revamped weekend schedule, both series will line up the field based on points in the standings.

Kevin Harvick will lead the Sprint Cup field from the pole position with Brad Keselowski second, then defending Darlington champion Carl Edwards, Kurt Busch and Joey Logano in Sunday night’s race.

The Xfinity Series race is scheduled for Saturday afternoon.
