He tells us the memories started flooding back when he heard about what happened. As we reported back in 2009 ... Tony got hit by the boxer after getting too close to him near the ticket counter at LAX.
Police told us both parties made citizen arrests on each other, and Mike was taken away in a squad car while Tony was taken to a hospital. BTW ... Tyson was not charged with a crime but settled with Tony for an undisclosed amount.
Tony says he and Mike have made up since their past scuffle, but he feels bad for him about what happened Wednesday ... and wants everyone to know Mike is a legend that shouldn't be messed with.
