Travis Pastrana is leaving NASCAR after this weekend's season finale Nationwide Series race at Homestead.
Pastrana announced his decision Monday on his Facebook page. He cited a lack of sponsorship and frustration over his struggles in NASCAR as his reasons for leaving the sport.
Pastrana is one of the most popular action sports stars in the world and a 17-time medal winner at the X Games. He first tried NASCAR in 2011 and was scheduled to make his Nationwide debut that July until he broke his leg in an X Games accident two days before the race.
It delayed his debut until last season, when Pastrana ran nine races.
He goes into Saturday's finale ranked 14th in the standings.
