Jacob Montalvo

Jacob Montalvo appears as the assigned referee in 87 archived UFC bouts currently loaded by PropBetEdge (historical coverage is still being backfilled, so this is not a career total) across 2011–2026. This profile treats officiating as context, not destiny: the rates below describe what happened in that historical sample and do not prove that the referee caused a finish, decision, pace change or judging outcome.

No externally sourced biography passed the identity check for this official, so the summary above is generated from our own archive rows only.

Important: “fight impact” here means historical context, not causation. A referee does not choose the matchup, fighter styles, skill gap or scheduled length, so finish and decision rates must be interpreted with sample size and those confounders in mind.
