Doc Gooden just couldn't wait 'til March to get a piece of his celeb boxing match opponent -- attacking Catfish Cooley at a press event -- and TMZ Sports has the video!!
The 54-year-old MLB legend and 29-year-old "Nitro Comedy Tour" star are set to square up for real March 7 at the Showboat Hotel in Atlantic City.
The duo met up for a press event Chima Steakhouse in Philly on Wednesday and started trading verbal jabs before Catfish said something that REALLY pissed Doc off.
