In case you didn't know ... Boris Margeta was banned from officiating any more 2012 Olympic matches ... after he disallowed a goal that should have counted in Spain's July 31st match against Croatia.
TMZ spoke to Boris and he tells us ..."It was very bad. After I saw the replay I knew I made a mistake." He adds, "My apologies to Spain's team."
Spain lost the game 8-7 and Croatia went on to take the lead in their bracket.
The good news, Spain's still in the running to medal ... they finished 3rd in bracket play, securing them a spot in the quaterfinals.
