Brad Keselowski's No. 2 Team Penske Ford team could face penalties this week after his Monster Energy NASCAR Cup Series ride failed post-race inspection at Phoenix Raceway on Sunday night.
The No. 2 failed weights and measures after Keselowski piloted it to a fifth-place finish.
No other cars failed post-race tech inspection. Ryan Newman's No. 31 race-winning Chevrolet, Kyle Larson's runner-up No. 42 entry and Kevin Harvick's No. 4 Ford will all head back to NASCAR's R&D Center in Concord, North Carolina, for further routine inspection.
