(AP) — NASCAR has adjusted the schedule for this weekend’s exhibition race at Bowman Gray Stadium in Winston-Salem in anticipation of more ice and snow blanketing the Winston-Salem area of North Carolina. The Clash was supposed to be a two-day event beginning Saturday with the main event held Sunday evening. To adjust, NASCAR has postponed all of Saturday’s on-track activity and will run the Clash as a one-day program Sunday. Times in the final session will determine their starting lineup for the main event and the last chance qualifier. — The Sunday 75-lap last-chance qualifier will offer two spots in the main event for those who didn’t finish in the top-20 in qualifying.
