MMA judge · scored in the loaded archive 2024–2026. 7 archived scorecards.
Jason Grenier has 7 orientation-resolved cards in the loaded archive. Below 40 cards a dissent rate moves several points on a single fight, so the counts are shown and the rate is withheld.
A dissenting card means this judge's card went to the fighter who did not win the bout. It does not say the card was wrong, and it is not evidence of a preference for any style, nationality or type of fighter.
Jason Grenier appears on one card on each of 7 archived UFC bouts currently loaded by PropBetEdge across 2024–2026. Historical coverage is still being backfilled, so this is an archived sample rather than a career total. Everything below is a description of what these cards contained. It is not an assessment of judging quality, and it is not evidence that this official favours any style, nationality or type of fighter.
No externally sourced biography is attached to this official. PropBetEdge does not generate one, and no personal detail appears here that is not derived from the loaded bout archive.

Everything above is a description of 7 scorecards currently loaded into the PropBetEdge archive. It is not a career record, not an assessment of judging quality, and not a claim that this official favours any style, nationality or type of fighter. Rates are withheld below 40 orientation-resolved cards and are only described as differing from the archive when a 95% test says the difference survives the sample size.
Fighter attribution is derived from each bout's recorded result rather than assumed from the order of the two numbers. Where a card cannot be oriented — every draw, and any bout whose cards contradict the result — the pair is shown as recorded and marked unattributed. See the methodology.
