NASCAR Cup champion Tony Stewart is retired from stock car racing.

But not from the dirt tracks.

Stewart’s hauler showed up to the Fairgrounds Speedway Nashville on Friday morning, and the World Of Outlaws confirmed on Twitter that the newly named NASCAR Hall of Fame driver is racing Friday.

Stewart told race officials he also plans to race Saturday. 

Veteran NASCAR drivers Kenny Wallace and Ken Schrader are also in the field. 

Stewart does not regularly run the Outlaws tour, but he has run in the series before and with success. The Indiana native won his first ever World of Outlaws race in July 2011.

Tony Stewart Racing does run the World of Outlaws Sprint Car Series regularly with Donny Schatz, a nine-time champion in World of Outlaws. 

According to his website, Stewart ran in a USCS Speedweek race in Lexington, Tennessee, on Memorial Day and won the event.

In August 2014, Stewart struck and killed fellow driver Kevin Ward Jr. in a sprint car race in upstate New York. The fatal collision happened after Ward Jr. crashed while racing Stewart. Ward Jr. jumped out of his wrecked car and began gesturing toward a motoring Stewart, whose car fishtailed before striking Ward Jr.

A grand jury did not indict Stewart for manslaughter or negligent homicide weeks after Ward’s death. The Ward family, led by Ward Jr.’s parents, filed a wrongful death lawsuit against Stewart that was settled for an undisclosed sum last year.

The World of Outlaws Sprint Car Series will race at the Fairgrounds Speedway Nashville Friday and Saturday nights, with on-track action starting at 4:30 p.m. with qualifying. Opening ceremonies are set for 7 p.m.
