UFC fighter Felice Herrig is taking the high road in her now infamous fight with Justine Kish -- saying she refuses to "talk s**t" about her opponent ... despite what happened in the octagon.
Herrig tells TMZ Sports she actually really likes Kish a lot and feels bad that she's blowing up in the media because of Sunday night's poo incident on live TV.
She actually calls for MMA fans to lay off Kish -- saying she's a really cool girl who doesn't deserve to be dragged through the mud.
The good news for Herrig .
