filled out the rest of its 2020 season. The schedule for the playoffs in the Cup Series saw no change in the order of races or the tracks on which they ran. With two races still to be made up because of previous cancellations, the Xfinity Series playoff opener was delayed one week, starting with the Alsco 300 at Las Vegas Motor Speedway. A second race was added at Talladega, the Ag-Pro 300, which was in the playoff. The truck series playoff schedule included the rescheduled INDYCAR weekend race at Texas Motor Speedway (Texas and INDYCAR agreed to remove all support races for that weekend, which was held on its regularly scheduled weekend) and a third race at Kansas Speedway. The first two races were to be at World Wide Technology Raceway at Gateway (which kept its date, like Texas part of the INDYCAR weekend and logistics made it part of the regular season) and Canadian Tire Motorsports Park (removed because of travel restrictions by the Canadian government; the same restrictions forced Canadian-based MLB, NBA, and MLS teams to move their games to the United States for the season and part of next season as well, along with all Canadian National Hockey League teams were put in one division for the 2021 season, as well as cancelling the INDYCAR race in Toronto) Changes to the regular season include a second Xfinity Series race at Richmond Raceway (had been originally removed for a Martinsville Speedway race) and the Truck Series returned to Darlington for the first time since 2011, while Richmond, which had originally been set for the cancelled April Cup meeting, was moved to the September race meeting. During the playoffs, tickets were available for the races at Darlington (8,000 spectators; first meeting of two Cup races behind closed doors), Bristol (hosted about 20,000 spectators of possible 30,000 at non-championship meeting; first championship meeting behind closed doors), Charlotte (7,500 seats), Kansas (8,400 seats), Talladega (which hosted 5,000 in the June meeting), Texas (about 50% capacity, or 50,000 seats; hosted July meeting with spectators), Martinsville (1,000, first meeting was behind closed doors), and Phoenix (about 20% capacity, or 8,400 seats). The Richmond and Las Vegas races were behind closed doors; the first date at the latter track was held before the pandemic, and only began admitting spectators for the relocated NHRA World Finals at its drag strip from 30 October to
