Bubba Wallace Tweets Call of Duty Joke, 'I'm Good' After Appearing to Faint

NASCAR driver Bubba Wallace tweeted that he's OK after appearing to faint following Sunday's race at Atlanta Motor Speedway:

The Gulag is a reference to Call of Duty, which sends players to a prison after dying in the video game. You can return after winning a one-on-one duel with another competitor.

It's a lighthearted joke after a scary moment following the Folds of Honor QuikTrip 500. Wallace reportedly suffered extreme fatigue in the hot temperatures, according to Matthew Mayer of CBS Sports.

Personnel checked out Wallace after the race:

He was later brought onto a stretcher before being released from the infield care center.

It was at least the second time Wallace has visibly suffered the effects of fatigue after a NASCAR race. He fainted after his first career Cup event in 2007 at Pocono Raceway.

The Richard Petty Motorsports driver finished in 21st place in Atlanta on Sunday after earning a top-10 finish in Bristol last time out. He ranks 22nd in the Cup Series standings.
