UFC Legend Mark Coleman Awake, Responsive After Saving Parents From Fire

UFC legend Mark Coleman is breathing on his own and talking to his family ... just days after he was airlifted to a hospital with life-threatening injuries sustained while rescuing his parents from a house fire.

Coleman's daughter, Kenzie, shared an emotional clip on Mark's Instagram ... just 2.5 days after the MMA great suffered smoke inhalation while saving his mom and dad from a giant blaze.

"I had to make a decision," Coleman said about the house fire from his hospital bed, "It was already horrible! I couldn't breathe!"

"I'm the happiest man in the world. I swear to God I'm so lucky! I can't believe my parents are alive!"

Unfortunately, his dog, Hammer, passed away ... and Coleman -- who retired from MMA in 2013 -- is completely devastated.

"I couldn't find Hammer!" Coleman said as he cried with his family.

A GoFundMe was set up for Coleman's loved ones as his daughters will take time off work to help him during his recovery. As of Thursday, over $68K was raised.
