Combat sports great Art "One Glove" Jimmerson -- who competed on the very first UFC card as a boxer -- has died, his family announced. He was 60 years old.
Jimmerson -- who famously wore just one boxing mitt in the UFC 1 match in 1993 -- came into the contest against Royce Gracie on a 15-fight win streak ... and fell to the MMA legend after tapping out in two minutes.
It's reported he wore one glove so he could punch with one hand and have the other free to grapple .
