The WWE fan sentenced to 10 days in jail for hopping the barricade at Night of Champions is definitely not NXT ref Drake Wuertz ... and Pro Wrestling Sheet obtained his mugshot to prove it.

Following the arrest of 37 year-old Oscar Ramirez, many viewers tweeted saying they thought it was a work -- because the guy look looked like Wuertz -- but cops say the whole thing was very real.

As we previously reported, Ramirez pled guilty to trespassing after he was taken into custody. WWE has since said they plan to prosecute trespassers to the fullest extent of the law.

Chris Jericho tweeted Tuesday about the WWE fan being sentenced ... saying, "Let this be a lesson to all…stay out of OUR ring!"

Hopefully this never EVVVEERRRRRRRRR happens again.

UPDATE 9:40 AM PST: Despite being sentenced to 10 days ... the jail website says Ramirez has already been released.
