Tony Gibson didn't get much of a celebration after his victory with Kurt Busch. Soreness from a passed kidney stone concerned him enough to visit a doctor.

Tests discovered the crew chief had never passed the kidney stone that sidelined Gibson during the April 19 race at Bristol, and the stone was a painful 7 millimeters.

So Gibson underwent a procedure Wednesday to remove the stone and had a stent placed from his bladder to his kidney. A day later he was on a plane to Alabama and was back at work Friday at Talladega Superspeedway.

Gibson says he was sore, but would rather be feeling poorly at the race track than be sitting at home.
