Hyder returning to pit box for No. 36 car

CONCORD, N.C. -- Crew chief David Hyder, fired from Michael Waltrip Racing last month, will return to the pit box next weekend at Dover International Speedway to guide the No. 36 Toyota driven by Jeremy Mayfield, Bill Davis Racing competition director Tommy Baldwin told ESPN.com Saturday.

Hyder is already working in the BDR shop, preparing a car to test Tuesday at North Carolina Speedway in preparation for Dover, Baldwin said.

Hyder was fined $100,000 and suspended indefinitely by NASCAR in the first week of the season after an illegal substance was found in the carburetor on the No. 55 Toyota prior to qualifying.

NASCAR will lift the suspension on May 30, opening the door for Hyder to join BDR.

Baldwin is relieved to bring Hyder on board. He'd been pulling double duty since March, serving both as crew chief for Mayfield's team and as the organization's competition director.

"Thank god," Baldwin said with a grin. "It's time for me to focus on the future of this organization."

Hyder was unavailable for comment.
