WWE has released a graphic video of Cesaro receiving stitches in his mouth ahead of emergency dental surgery as a result of an injury he sustained at No Mercy.
During the RAW tag team championship match between Rollins/Ambrose and Sheamus/Cesaro, Ambrose delivered a slingshot that sent Cesaro head first into the ring post. The severity of the impact left the Swiss Superman with blood pouring from his mouth.

After getting checked out at ringside, Cesaro admirably returned to the ring, but Rollins and Ambrose picked up the win and retained the titles after a hard fought match.
