Professional Fighters League star Mark Martin says he's NOT contemplating retiring after his eye popped out during his fight last week ... telling TMZ Sports he's 100% committed to returning to the cage -- as long as he's physically able to.
"Showtime" suffered a broken orbital and blood around his retina after the first round of his bout against Dilano Taylor on Friday ... with his eye coming out of its socket after he blew his nose.
Yes, it's tough to watch.
