Sheamus is currently dealing with a concussion, according to the latest Wrestling Observer Newsletter. It's believed to have happened during The New Day vs. Sheamus, Cesaro, and Drew McIntyre on SmackDown last week.
Sheamus did not appear on either of this week's Superstar Shake-Up editions of RAW and SmackDown. The concussion would explain his absence from the SmackDown main event where Cesaro teamed up with Rusev and Shinsuke Nakamura in a losing effort against Kofi Kingston, Xavier Woods, and Kevin Owens.
