Thanks to Wrestlezone reader Lewis Butler for the following:
During a six man tag team match on RAW last night, Alberto Del Rio had Sin Cara on the mat and pulled his mask off, and his face was visible to fans for a few moments. Sin Cara's face was briefly revealed to home viewers, and some audience members sitting on the hard camera side of the arena. No mention of this was made on television besides saying Alberto was 'attempting' to do it, not that he was actually successful in his actions. You can view the photo below.
