Krissie Newman, the recently separated wife of NASCAR star Ryan Newman tweeted that she was "praying for a safe race," just hours before he was involved in a devastating crash at the Daytona 500 which left him seriously injured.

On the race's final lap Monday evening, Newman who was leading the race was spun out, hitting the wall hard and then flipping into the air before his car caught fire.

His injuries were serious but not life-threatening, NASCAR said in a statement. He remains in the hospital.

Krissie sent the tweet in response to a question from a follower about whether she would be watching the race, the first of the NASCAR season.

"I am," she said. "Would love to see my girls in [Victory Lane] but always praying for a safe race."

Newman also posted a photo of her by the ocean in response to being asked where she was watching from, to which another follower replied: "You lie, you aren't even watching." She replied with a winking emoji.

After the crash, Krissie Newman tweeted simply "Omg." She has not commented further since.

Ryan and Krissie Newman announced that they would separate last Thursday after 16 years of marriage. Krissie, 42, described the split as amicable in a statement, saying that they will remain friends and continue to raise their two daughters together.

Ryan is currently being treated at the Halifax Medical Center in Daytona Beach.
