Furniture Row Racing has announced that Jay Guy is to leave his role as crew chief.
The decision, taken by mutual agreement, was confirmed in a short statement by team general manager Joe Garone as the outfit turns its focus to the 2010 Sprint Cup season.
That season will see the team take on the challenge of running a full season in NASCAR's premier category, with Regan Smith on driving duties having run a part campaign this year.
"We wish Jay all the best - he is a good friend who worked hard to help bring us to where we are at," said Garone. "Jay was a true asset to our organization the past three years and we support him with his new opportunity.
"The future is exciting at Furniture Row Racing. We are continuing to expand our resources to run a full schedule next year and are on the right track towards giving our driver Regan Smith the best tools possible to race competitively on a weekly basis."
