Eddie George: Herschel Walker Taught Me '2-Inch Punch' ... Demos On TMZ Photog!

Eddie George is trying to get on Bruce Lee's level ... 'cause he's mastereing the "2-inch punch" -- and tested it out on a TMZ photog!

Here's the backstory ... George got an MMA tutorial from Herschel Walker in between takes at a "Heisman House" commercial shoot earlier this week.

Walker worked on the technique with George ... and he was all excited to try it out when our photog inquired about it at LAX.

FYI -- our photog fully consented!!!

Meanwhile, here's Bruce doing the 1-inch version.
