Possible issues with Hamlin’s No. 11

During post-race inspection, NASCAR found what the sanctioning body called “possible issues” with several rear firewall block-off plates on the third-place No. 11 Joe Gibbs Racing Toyota driven by Denny Hamlin.

The parts were confiscated and taken to NASCAR’s research-and-development center in Concord, North Carolina, for further inspection and evaluation.

If penalties are warranted, they are likely to be announced during the coming week, as is NASCAR’s custom.
