Travel issues for teams leaving the Charlotte area have forced NASCAR officials to alter the on-track weekend schedule in Mexico City.

July 12 — NASCAR Xfinity Series Race at Sonoma, Sonoma, Calif. July 19 — BetRivers 200, Dover, Del. July 26 — Pennzoil 250, Speedway, Ind. Aug. 9 — Mission 200 At The Glen, Watkins Glen, N.Y. Aug. 22 — Wawa 250 Powered by Coca-Cola, Daytona Beach, Fla.

As a result, NASCAR officials have chosen to delay the planned Cup Series practice session, rescheduling them for later in the afternoon. They have also pushed all NASCAR Xfinity Series practice sessions from Friday to Saturday. Additionally, the first of two NASCAR Mexico Series races will now run a few hours earlier on Friday.
