Herrera made his mixed martial arts (MMA) debut in 2011 and had 13 fights over a seven-year career, four of which were in the UFC.
The Colombian reportedly perished in a motorcycle accident near Tampa, Florida.
“Geane, you will always be in our hearts,” Herrera’s family stated on a GoFundMe page.
“Geane leaves behind a 16-year-old son, his 3-month pregnant girlfriend, mother, father, sisters, a brother and a family that loves him and will deeply miss him.”
Herrera made his UFC debut against Ray Borg in 2015, losing by unanimous decision, although he went on to defeat Joby Sanchez in his second fight.
