Daniel CormiervsStipe Miocic

The setup

UFC 226 in July 2018 was the heavyweight title bout between defending champion Stipe Miocic (three-defense champion, 18-2 in MMA) and Daniel Cormier (moving up from light heavyweight where he held the LHW title). Cormier was attempting to become the first simultaneous LHW + HW UFC champion since Conor McGregor's two-division moment in 2016.

Pre-fight context:

• Miocic's three defenses: Overeem, JDS rematch, Ngannou — the most-defended modern heavyweight reign.
• Cormier's LHW reign: continuing after Jon Jones's USADA-related vacating of the title.
• The size difference: Miocic was a natural heavyweight; Cormier was a smaller heavyweight moving up from LHW.

The fight

The bout ended in round 1.

• At 0:00: bell rings. Miocic moved forward with his standard boxing pressure.
• At 0:30: Cormier and Miocic clinched. Both fighters established underhooks.
• At 4:00 of round 1: Cormier landed a counter-check-hook off Miocic's punching combination. The strike dropped Miocic to the canvas.
• At 4:33: Cormier followed up with a single hammer-fist strike on the grounded Miocic. Referee Herb Dean stopped the bout at 4:33 of round 1.

The technical signature:

• The counter check hook: Cormier threw a short check hook off Miocic's commitment to a striking combination. The strike traveled in a tight arc and connected on Miocic's temple.
• Hip drive: Cormier's wrestling-derived hip rotation generated the power.
• Single-shot finishing: a single clean strike ended the bout — a rarity at heavyweight championship level.

The aftermath

The result:

• Cormier became simultaneous LHW + HW UFC champion: fourth simultaneous two-division UFC champion (after McGregor 2016, Cejudo 2019, Nunes 2018).
• Miocic's title reign ended: but his career continued at championship level.
• The trilogy with Miocic: produced two more bouts.

The trilogy:

• UFC 241 (August 2019): Miocic TKO Cormier round 4 — the body-shot setup that reclaimed the heavyweight title.
• UFC 252 (August 2020): Miocic UD Cormier — the trilogy-closing five-round chess match. Cormier's retirement fight.

The trilogy ended 2-1 in Miocic's favor (Miocic's UFC 241 and UFC 252 wins vs Cormier's UFC 226 KO).

The historical significance

The UFC 226 bout's significance:

• Two-division championship at heavyweight: the most-significant simultaneous two-division UFC championship achievement (more demanding than McGregor's FW + LW or Cejudo's FLW + BW because of the size difference).
• Cormier's career capstone: after years of falling short against Jon Jones, the two-division championship gave Cormier the unambiguous championship credential.
• Miocic's championship-rounds analysis: the first-round KO demonstrated that even Miocic's three-defense reign could be ended by a single strike at the right timing.

The Cormier two-division title combined with his Olympic-level wrestling pedigree (2004 Olympic team 4th place) makes him one of the most-decorated combat-sports athletes to have competed in the UFC. The UFC 226 KO was the technical and narrative peak of his career.

The bout is on every list of significant UFC heavyweight title changes and is the canonical two-division-champion case study (alongside McGregor's UFC 205, Cejudo's UFC 238, and Topuria's UFC 317).
