WORRIED WIFE DERAILS DALE'S NASCAR COMEBACK

NASCAR racer Dale Earnhardt Jr.’s wife is putting the brakes on any plans the iconic wheelman has of returning to the track after quitting six years ago due to a bunch of brain-cracking concussions that left him barely able to walk or climb stairs.

Sources say Dale, who hits 50 on Oct. 10, has his missus, Amy, in a tizzy after he climbed behind the wheel and scored an impressive seventhplace finish in a low-level NASCAR Xfinity Series race at Bristol Speedway Sept. 20. Now worried Amy fears he’s going to rattle his noggin and suffer permanent damage if he races again!

“Dale would love to do a few races a year and get that adrenaline rush again,” squawks a friend.
