Dale Earnhardt Jr. will have a new crew chief starting with this weekend's race at Dover. The team said Thursday that Tony Eury Jr. was replaced as crew chief of Earnhardt's No. 88 team. The two are cousins and have worked together Earnhardt's entire career. They left Dale Earnhardt Inc. last season to drive for Hendrick Motorsports, but they've yet to find consistency despite driving for NASCAR's top team.
