The man who claims he was attacked by Johnny Manziel and his "entourage" last week says he's still in pain from the alleged hotel beatdown ... and says he's got pics to prove it.
TMZ Sports spoke with Chris Gonos ... who claims his left elbow was jacked up by Johnny's crew during a fight at The 9 hotel in Cleveland late Friday night.
Gonos says the picture shows severe swelling and a nasty bruise -- but claims he also suffered a swollen lip and and injuries to his eye.
Gonos says he's not sure who hit him -- but he's confident the assailant was part of Johnny's crew.
Police are investigating the incident ... but so far, no arrests have been made.
As for Johnny, he tells a very different story ... saying he was "accosted by a very aggressive man and his associates" at the hotel that night.
Manziel also says he was never rolling with an "entourage."
