NASCAR issued L1 penalties against two teams in the Monster Energy NASCAR Cup Series following last Sunday's race at Phoenix International Raceway.

The No. 2 team of Team Penske was penalized for a violation of sections of the NASCAR Rule Book for failing post-race general inspection measurements. As a result of the penalty, Brad Keselowski's fifth-place result in the Camping World 500 was declared an encumbered finish.

Crew chief Paul Wolfe was fined $65,000 for the infraction and has been suspended for the next three points-paying races. Keselowski was docked 35 driver points and the team lost 35 owner points.

The No. 4 team of Stewart-Haas Racing was also hit with an L1 penalty. The team was found to be in violation of sections I-4 for an unapproved track bar mount and support. Kevin Harvick's sixth-place finish at Phoenix was also ruled encumbered.

Harvick's crew chief Rodney Childers was fined $25,000 and suspended for this weekend's race at Auto Club Speedway. The team assessed a loss of 10 driver and owner points for the infraction. Harvick's penalty drops him to eighth in the championship standings behind Chip Ganassi Racing's Jamie McMurray.
