Trevor Bayne, who is currently fourth in the NASCAR Nationwide Series points standings, and earned his first series victory last fall at Texas Motor Speedway, will miss Friday night's race at Texas due to lack of sponsorship.
Bayne was not listed on the original Entry form for this week's race and on Tuesday Roush Fenway Racing officials confirmed he is not running the event.
The missed race could all but end his quest at a series title this season. There was no immediate comment from RFR or Bayne.
Bayne had been hoping to run the full season in Nationwide and compete for the series championship. He had one top-five and three top-10 finishes in the first five races of the 2012 season.
Bayne is scheduled to drive the No. 21 Wood Brothers Racing Ford in Saturday night's Sprint Cup Series race at Texas.
