CHARLOTTE, N.C. (AP) — Joe Gibbs Racing will not appeal the penalty levied against Denny Hamlin's team for failing a post-race inspection at Indianapolis Motor Speedway.
Crew chief Darian Grubb was suspended six weeks and fined $125,000, and car chief Wesley Sherrill was also suspended six weeks. Hamlin and Joe Gibbs were each docked 75 driver and car owner points.
JGR had initially said it would appeal the penalty, which was issued because the firewall was not sealed in Hamlin's No. 11 Toyota following his third-place finish at Indy. The team said Thursday it would not appeal.
Grubb and Sherrill are both cleared to return to competition at the opening race for Chase for the Sprint Cup championship, Sept. 14 at Chicago.
