Robby Gordon's third place finish in the Coca-Cola 600 at Lowe's Motor Speedway is under question after scrutineers retained his car for further investigations after the race was called 173 laps short of its anticipated 400 target.

Gordon's best result for many years may not be under threat due to NASCAR's policy of fining and suspending guilty parties rather than disqualifying cars, but questions were raised during post-race inspection when officials thought there might be an issue with the rear axle housing of the #7 Toyota.

NASCAR is taking the housing to its research and development centre in Concord, North Carolina., for further examination. If any penalties are forthcoming they will be announced later this week.

Gordon's third place was as unexpected as David Reutimann's maiden Cup Series win, but resulted from a similar tactical decision by his crew, keeping the veteran out on track while many of his rivals opted to pit for fuel and tyres under caution on lap 222.
