Kurt Busch crew chief Tony Gibson has emergency appendectomy

Kurt Busch's crew chief had an emergency appendectomy that could delay his arrival in New Hampshire for this weekend's playoff race. Tony Gibson posted Wednesday on Facebook that he was home and resting a day after the procedure.

Stewart-Haas Racing said Gibson plans to be at New Hampshire Motor Speedway for Sunday's race, but will not leave North Carolina until he's able. The team will have engineer Jeff Klausmeier ready as interim crew chief should Gibson miss any time. SHR vice president of competition Greg Zipadelli will also take on a larger role with the No. 41 team, the team said.
