The MMA fighter who was struck by a car and lost his leg in a hit and run accident may have been wearing headphones that drowned out the sound of the car approaching ... officials say.
The story is absolutely heartbreaking ... 25-year-old Jordan Parsons was crossing a street in Florida early Sunday morning when he was struck by a Range Rover Sport and left with "extreme injuries."
Officials say the RR hit Parsons and fled from the scene -- leaving him with a severe leg wound.
Emergency responders raced to the scene and applied pressure to the leg in hopes to save it -- but the wound proved too severe and it was amputated at a nearby hospital.
Officials say it's unclear who had the right of way -- Parsons or the Range Rover.
Still, the driver should NOT have fled -- and now cops are offering a $1,000 reward for info that leads to an arrest.
Parsons -- who trained with superstars like Rumble Johnson and Rashad Evans -- is still in a coma, according to Evans and a GoFundMe page has been set up to raise money for his medical bills.
1:28 PM PT -- The Delray Beach Police Department released a picture of the mirror that fell off the Range Rover at the scene of the crash.
