JJ Aldrich vs. Regina Tarin: women's flyweight prelim preview at Noche UFC

The setup

JJ Aldrich (15-7-0) and Regina Tarin (8-0-0) meet at women's flyweight on the prelims when Noche UFC arrives at Desert Diamond Arena in Glendale on Saturday, September 12, 2026, scheduled for three rounds.

Our schedule tables list 13 bouts on the card; this one is filed under the prelims. The bout is listed as announced in the PropBetEdge schedule.

The question this preview works through is simple: does either side bring a measurable edge, or is this a matchup the data leaves open? PropSports career averages are on file for both fighters, and the archive holds 17 completed UFC bouts for JJ Aldrich and 1 completed UFC bout for Regina Tarin.

Tale of the tape

• Record: JJ Aldrich 15-7-0 · Regina Tarin 8-0-0
• Age: JJ Aldrich 33 · Regina Tarin 21
• Height: JJ Aldrich 5'5" · Regina Tarin 5'7"
• Reach: JJ Aldrich 67.5" · Regina Tarin 66"
• Stance: JJ Aldrich Southpaw · Regina Tarin Southpaw
• Listed weight: JJ Aldrich 125 lbs · Regina Tarin 130 lbs

Reach is close to even (67.5" to 66"), so neither fighter starts with a length edge and the striking exchanges begin from the same distance. Regina Tarin is the younger by 12 years (21 to 33). Age on its own tells you little at this level; it reads better alongside the layoff figures in the form section. Both fight southpaw, so lead hands mirror and the rear-hand exchanges are conventional. Listed weights differ: Regina Tarin at 130 lbs to 125 for JJ Aldrich. Listed weight is a roster figure, not a weigh-in, so it is a note rather than an edge.

Style and statistical matchup

JJ Aldrich lands 3.92 significant strikes per minute at 46% accuracy; Regina Tarin lands 7.6 at 47%. That 3.68-per-minute gap in Regina Tarin's favour is a real pace differential: over three rounds it compounds into a scorecard edge unless the lower-volume fighter is landing the more damaging shots. On the other side of the exchange, JJ Aldrich absorbs 4.34 per minute with 61% striking defence and Regina Tarin absorbs 7 with 57%.

On the ground, JJ Aldrich averages 0.7 takedowns per 15 minutes at 25% accuracy and defends 67% of attempts against her; Regina Tarin averages 1 at 33% and defends 50%. JJ Aldrich's 17-point takedown-defence edge is the grappling number to weigh: it limits how often the fight leaves the striking exchanges.

All of these are career-to-date PropSports snapshots at capture, not as-of figures for this bout: they describe each fighter across every opponent, which is why the archive form above is read alongside them rather than replaced by them.

Round-level stats exist for 48 archived rounds of JJ Aldrich's: 922 of 1999 significant strikes landed (46%), 19.2 per round, 11 of 43 takedowns, 39:02 of control time. That is a small sample and is offered as colour, not as a rate.

What could break the angle

The counter-case is mostly about sample. Regina Tarin has only 1 archived UFC bout in the PropBetEdge database, so the form read is thin. Career averages are career-to-date snapshots at capture; they include fights outside this matchup context and are not as-of figures. There is also no odds snapshot in PropBetEdge data for this bout, so nothing above can be checked against a market yet; the read describes what to look for, not where value sits. A late weigh-in miss, a replacement or a change in scheduled rounds would each invalidate parts of it.

Final read

On the data, neither fighter carries a material edge into this one; the tape is close and the archive does not separate them. The uncertainty is mostly about coverage: archive shorter than 3 bouts for Regina Tarin. What to monitor: the three-round format holding, the weigh-in, and once a price exists, where the fight goes the distance, method of victory and significant strikes markets open relative to this read. No model price or market line exists in PropBetEdge data for this bout, so this is not a pick; the Bettor's Edge panel above carries the impact score and the markets connected to the evidence.
