LOS ANGELES (CBS) -- Dwayne Johnson is home after hernia surgery.
The actor tweeted a photo of himself in a hospital bed Tuesday, the Associated Press reported. In the photo, the star shows off his muscles while wearing a Superman T-shirt and a hospital bonnet.
Johnson wrote that the doctor repaired three hernia tears. His press representative, Alan Nierob, said Johnson is now recovering at home.
The 40-year-old Johnson was forced to bow out from attending the Monday night L.A. premiere of his new movie, “Pain and Gain,” co-starring Mark Wahlberg and directed by Michael Bay.
While it’s unclear what exactly caused Johnson’s injury, the action star has certainly been keeping up a tough physical regime with his latest projects.
Earlier this month, Johnson went back into the wrestling ring to face off against WWE champion John Cena.
In “Pain and Gain,” Johnson plays a body builder criminal who works out around the clock. His other most recent film roles were in “G.I. Joe: Retaliation” and the action-packed “Snitch.”
His next release is “Fast & Furious 6,” due out May 24.
“Pain and Gain” opens in theaters on Friday.
