David Fero will serve the suspension for this weekend’s regular season finale at Daytona International Speedway after Chastain lost an axle on his car during last Sunday’s Cup race.

At 185 points behind the cut line, Chastain must win at Daytona on Saturday night (7 p.m. ET, NBC) to make the Cup playoffs.

Several penalties from Michigan and WWTR involved lug nut violations from post-race inspection.
