#3. Cesaro - WWE No Mercy 2017

Cesaro is perhaps the toughest Superstar in WWE. While there have been numerous occasions to show it, none stands out as much as his tooth accident at No Mercy 2017.
Cesaro and Sheamus faced Seth Rollins and Dean Ambrose/Jon Moxley for the RAW Tag Team Championships at WWE No Mercy 2017. A botched moment saw Cesaro's two front teeth get jammed up 3-4mm into his gums during the match.
It required a surgical procedure, but that didn't stop Cesaro from finishing the match anyway. Not only was it a great match, but Cesaro was the most talked-about WWE Superstar coming out of a pay-per-view that featured Roman Reigns vs. John Cena and Brock Lesnar vs. Braun Strowman.
Former WWE Superstar Matt Morgan revealed on the WrestlingInc podcast that Cesaro reportedly got a standing ovation backstage after the match. The level of toughness Cesaro showed to not only finish the match but also have a great one speaks volumes about his ability in the ring.
It was further proof of why Cesaro is one of WWE's most underrated Superstars.
