Michael Waltrip Racing, still trying to find its way out of a terrible start to its first season in NASCAR Nextel Cup racing, turned to Jason Burdett to replace crew chief Matt Borland on Dale Jarrett's No. 44 Toyota.
It was the third crew chief change for the Waltrip team in less than a month.
Borland, who came to the Waltrip team from Penske Racing South, where he was crew chief for Ryan Newman, turned down the job as the new team's technical director and left the organization, according to a team spokesman.
Burdett, who worked with Jarrett last year at Robert Yates Racing, will move into his new duties after a brief period to get acclimated to his new team.
Meanwhile, Derrick Finley, who has been working as the lead engineer on team owner Waltrip's No. 55 car, will act as the interim crew chief for Jarrett this week at Richmond.
Jarrett, the 1999 Cup champion, goes into the Cup race at Richmond International Raceway 37th in the season points and will have to qualify for Saturday night's race on speed after using up all six of his former champion's provisionals for the season. ...
