KANNAPOLIS, N.C. – Stewart-Haas Racing will swap the teams of Danica Patrick and Kurt Busch after this Sunday's race at Martinsville Speedway.
Tony Gibson and the crew he has had since 2002 will move to Busch's No. 41 team. Daniel Knost will move his group to Patrick's No. 10 team as interim crew chief.
Busch won at Martinsville in March and earned a spot in the Chase for the Sprint Cup championship, but was eliminated after the first round. He and Knost have not meshed well and squabbled at times over the radio.
Patrick has shown marked improvement under Gibson the last two months, and led seven laps late at Talladega on Sunday.
SHR gave Kevin Harvick the crew from Tony Stewart's team at the start of the Chase.
