Brad Keselowski and Trevor Bayne will each lose 15 minutes of practice time Friday at Bristol Motor Speedway this weekend because of infractions last weekend at Texas Motor Speedway.

Keselowski's No. 2 Team Penske Ford and Bayne's No. 6 Roush Fenway Racing Ford each flunked NASCAR's laser inspection system three times at Texas and as a result their respective teams were docked 15 minutes of practice this weekend.

Bayne's three failures all came in pre-race inspection, while Keselowski's all came prior to qualifying.
