NASCAR star Dale Earnhardt Jr. has made it to the Olympics.

Earnhardt tweeted early Tuesday that he arrived safely in South Korea. He is expected to make his Olympic broadcasting debut for NBC Sports later this week.

Earnhardt said before the Daytona 500 on Sunday he would help provide coverage for the four-man bobsled event at the PyeongChang Games.

Earnhardt retired from full-time racing last year and signed with NBC Sports to cover NASCAR and other events.

He served as grand marshal for the Daytona 500, sitting out "The Great American Race" for the first time since 1999. Austin Dillon won the race 17 years to the day that Earnhardt's legendary father died in a last-lap wreck at Daytona.
