While battling Kane in a Last Man Standing Match on Raw, Roman Reigns sustained a cut on his forehead that required six staples.

“We brought Roman Reigns back to the trainer’s room after he sustained a laceration to his forehead when his forehead hit the ring post,” said WWE physician Dr. Chris Amann. “We cleaned him up real well and put in six staples to close the wound. He’s going to be cleared for SmackDown on Friday.”
