NASCAR has penalized driver Chris Buescher and his Roush Fenway Keselowski Racing team for illegal modifications to the bumper of his No. 17 Ford at Kansas Speedway.

Buescher drops from playoff hopeful on points to a must-win situation after NASCAR found irregularities following the Kansas race.

Chris Buescher has been penalized 60 points after NASCAR officials found his car was assembled improperly after Sunday’s race at Kansas. Buescher’s car was taken back to the NASCAR R&D center where officials said it exceeded the maximum reinforcement allowed for its front bumper cover.
