The 22-year-old told officers that she had been stabbed by her UFC fighter brother, adding that her older sister was in the house and had also been attacked in the stabbing frenzy.

The 31-yearold fighter could face life in prison or even the death penalty under Florida law if convicted.

Rivera had fought three times in 2020, defeating Ali AlQaisi, but lost to Giga Chikadzie and Andre Ewell.
