Jim Ross reported on Twitter earlier today that Cesaro (Claudio Castagnoli) is having shoulders issues that will likely require surgery.
Cesaro was not advertised for a match on today's Survivor Series but could have fit into the ten person elimination match.
Cesaro is coming off one of the better television matches on Raw in several months in the quarterfinal match in the WWE title tournament where he lost to Roman Reigns.
If he is to undergo surgery, that would be next on the list that includes Seth Rollins and Randy Orton as key performers with the company undergoing surgery and out for a significant length of time.
Ross on Twitter about an hour ago tweeted, "Hearing that @WWECesaro is having shoulder issues that will likely require surgery soon. If true, we wish him our best. Quality person."
