Robert Yates Racing told its organization on Monday that its two Nextel Cup crew chiefs, Tommy Baldwin and Slugger Labbe, would no longer be with the team, a source has told NASCAR.COM. 

Veteran crew chief Butch Hylton is rumored to be Jarrett's crew chief for this week's Allstate 400 at the Brickyard.

And so Jarrett loses yet ANOTHER crewchief.

Supposedly Baldwin will be heading back to Bill Davis Racing  while Slugger Labbe is looking at other options.

Hmmm.... who needs a veteran crewchief??  I think Labbe might be reuniting with Michael Waltrip again.
