Greg Erwin has been replaced as crew chief for Jack Roush Racing’s No. 16 Sprint Cup Ford and driver Greg Biffle effective the LENOX Industrial Tools 301 at New Hampshire Motor Speedway. This decision follows a 21st-place finish in the Quaker State 400 at Kentucky Speedway.

The finish dropped Biffle to 14th in points, 33 behind 10th place, and a guaranteed spot in the Chase.

Matt Puccia will replace Erwin as Biffle’s crew chief. Puccia began at RFR in 2004 and most recently worked in their research and development program. Up until this season, he served as crew chief for Paul Menard in the Nationwide Series, leading the No. 98 team to 19 top 10 finishes. The team finished fifth in Nationwide points.

He also served as crew chief for the RFR’s no. 50 Camping World Truck Series team, which was driven by David Ragan and Carl Edwards, among others. He also led Erik Darnell to victory in the No. 99 truck in 2008.

Team owner Jack Roush said:

Matt Puccia has been a very effective and successful crew chief with the organization in both the Nationwide and Camping World Truck Series. Most recently he has led the research and development efforts for our superspeedway program which helped put David Ragan in victory lane in Daytona. This is a natural progression of our crew chief development and I have every confidence that he will do well in this new role. Greg Erwin has made a significant contribution to our engineering efforts and our program is better because of him.

Biffle added:

I am excited for the opportunity to work with Matt Puccia. Greg Erwin led this team to the Chase the past three years and I look forward to Matt doing the same.

No word on what Erwin’s new role will be.
