Team Penske and driver Brad Keselowski will be without the services of crew chief Paul Wolfe for the next two events on the Monster Energy NASCAR Cup Series schedule after a penalty issued to the team was upheld Wednesday.

The National Motorsports Appeal Panel confirmed the L1 penalty against the No. 2 team for failing post-race inspection at Phoenix in March. The team was found to be in violation of Section of the NASCAR Rule Book, which provides specifications for measurements at the Laser Inspection Station.

Keselowski was docked 35 championship driver points, Team Penske was docked 35 championship owner points, and Wolfe was suspended for three races. The team was also fined $65,000 as a result of the penalty.

Wolfe sat out the Auto Club 400 and returned at Martinsville while the team's appeal was pending. Wolfe will be eligible to return May 7 at Talladega Superspeedway. 

Keselowski is locked into the NASCAR Playoffs with two victories this season.
