Last week troubled NFL free agent Antonio Brown was caught on video exposing himself to female hotel guests in Dubai [click here if you missed that].
This week Antonio is being accused of fraud for selling a fake Richard Mille watch...
From TMZ
In the lawsuit, obtained by TMZ Sports, Ryan Kane says Brown assured him the watch -- allegedly an RM 011 model -- was real ... and said it had a value "in excess of $400,000."
Kane says he bought it based on Brown's claims -- wiring the $160,000 to Brown's company -- but he learned a few weeks later the thing was a fake.
Kane says in the suit that he took it to a watch appraiser to have it authenticated and appraised for insurance purposes -- but claims the guy delivered him some bad news while he was there ... it was worth only a couple hundred bucks.
Kane says after he asked around, he learned that Brown had bought the fake watch -- and three others like it -- from a dealer in Dubai earlier this year for less than $500 apiece.
Kane is suing Brown for fraud and more ... seeking to get his money back plus interest.
