JR Motorsports and its competition director of five years, Tony Eury Sr., have announced the decision to amicably part ways, effective Friday.
Eury is a winner of 55 NASCAR races in both the Nationwide and Sprint Cup Series as a crew chief. He has 28 years in the NASCAR industry, the last five of which were served as competition director and crew chief for JR Motorsports. The company has amassed all nine of its victories under Eury’s watch. JR Motorsports’ last victory came on September 4, 2010, with driver Jamie McMurray.
In an effort to improve performance, a crew chief swap was implemented in April between Eury Sr. and Bruce Cook. Cook took over the company’s flagship No. 88 team driven by Cole Whitt, while Eury turned his attention to the partial entry No. 5 team driven by Dale Earnhardt Jr. and Ron Fellows while still serving as competition director. Whitt responded with two top-fives and eight top-10s in 19 races, while the Earnhardt/Fellows duo scored fifth-place finishes in three of its four races.
The No. 5 entry has no more races scheduled in 2012. Eury Sr.’s son, Tony Eury Jr., remains crew chief for JR Motorsports’ No. 7 Chevrolet and co-owner of the company with Earnhardt Jr. and Earnhardt-Miller.
Eury came to JR Motorsports in 2007, compiling seven wins, 48 top-fives and 86 top-10s as crew chief of the No. 88 team. Prior to that he spent 21 years at Dale Earnhardt Inc., where he won two Nationwide Series championships with Earnhardt Jr. in 1998 and 1999.
