Crew chief Tony Gibson undergoing surgery for kidney stone


Two weeks ago, Tony Gibson, the crew chief to Stewart-Haas Racing’s Kurt Busch, thought he had successfully passed his second kidney stone in 33 days, an ailment that kept him from working the No. 41’s pit box during the rain-delayed race at Bristol Motor Speedway.

Not so fast.

Upon further review, the stone hadn’t been passed. Three days after he successfully directed Busch to his first win of 2015 at Richmond International Raceway, Gibson tweeted Wednesday he was undergoing “little surgery” to have the stones officially removed.

The procedure comes two days before the Sprint Cup Series takes to the track at Talladega Superspeedway to prepare for Sunday’s Geico 500.
