It's been two weeks since Kayla Harrison went under the knife after suffering a serious injury, which forced her out of her UFC 324 co-main event fight with Amanda Nunes ... and now the featherweight champ is showing off her gnarly scar for the first time.

It's the first significant update we've received on Harrison since she posted an emotional video on Instagram after the operation, where she apologized to Nunes for missing the highly anticipated bout.
