Overview

• The right-front wheel detached on Lap 385 at Bristol as Denny Hamlin made contact with AJ Allmendinger, resulting in a crash.
• NASCAR issued an immediate two-lap penalty to the No. 11 and is evaluating the cause under its strict wheel-loss protocol.
• Under the rule, the jackman and tire changer face two-race suspensions, which would apply to New Hampshire and Kansas if imposed.
• Hamlin and crew chief Chris Gayle contend contact and prior wall damage, not a pit-stop error, triggered the failure.
• Joe Gibbs Racing says it can cover any sidelined roles as Hamlin enters the Round of 12 with a 26-point cushion above the cutline.
