Kurt Busch's crew chief Tony Gibson has emergency appendectomy

Kurt Busch's crew chief Tony Gibson could miss a portion of the upcoming Sprint Cup Series race weekend at New Hampshire Motor Speedway after having an emergency appendectomy Tuesday.

Stewart-Haas Racing confirmed that team engineer John Klausmeier will guide the Stewart-Haas Racing No. 41 crew in Gibson's absence and that competition director Greg Zipadelli will have an increased presence with the team. The team said that Gibson will get to the track once he feels physically able to work, and that could be as early as Friday morning or as late as Saturday afternoon. Practice and qualifying are scheduled for Friday with additional practice scheduled for Saturday.

The team would not comment on why Gibson would miss part of the weekend, but Gibson posted on Facebook that he had his appendix removed:

"Thanks everyone for the prayers, calls, texts and Facebook messages. Got home from the hospital last night. Just really sore today. Who needs an appendix anyway????"

Busch finished third in the Chase for the Sprint Cup opening event Sunday at Chicagoland Speedway. The 2004 Sprint Cup champion is fifth in the standings.
