Glover Teixeira comes in 10 pounds heavier as he and Mauricio “Shogun” Rua make boxing debuts at Spaten Fight Night 3

What happened: Glover Teixeira and Mauricio “Shogun” Rua made weight Friday for their Saturday boxing match at Spaten Fight Night 3, with Teixeira landing 10 pounds heavier than Rua, according to Yahoo Sports’ weigh-in report.

Why it matters right now: Teixeira and Rua are both best known for their UFC careers, and the bout represents a rare late-career shift into a pure boxing setting. For fans and for the fighters themselves, the weigh-in numbers are a first tangible sign of how the matchup will be framed, especially when it comes to power and physicality carried into the ring.

The weight difference: The reported 10-pound gap means Teixeira will enter the contest with a larger listed frame than Rua. In practical terms, the heavier fighter often carries advantages tied to strength and reach through clinch and punch-to-punch exchanges, though boxing also demands conditioning and timing that do not automatically scale with weight.

The matchup context: Rua and Teixeira are former UFC champions, and this fight is described as their boxing debuts. That makes the event more than a novelty, it is essentially a two-way test of adaptation, asking whether their striking instincts built in MMA can translate cleanly when the rule set removes grappling and changes the rhythms of offense and defense.

Event picture: Spaten Fight Night 3 is staged as a boxing night featuring this marquee crossover. With the weigh-in completed, the next major checkpoint is not another measurement but how each fighter responds over the first rounds, particularly whether they can establish range early and manage the speed gap that can emerge when a boxer-first approach replaces mixed-martial-arts movement patterns.

What to watch next: The most important questions for Saturday are how quickly Teixeira and Rua settle into boxing-specific footwork, guard discipline, and punch selection. The weight advantage, while notable, is only one variable, and observers will likely look for whether Teixeira can use size to disrupt Rua’s balance, or whether Rua can offset physical differences with timing and combinations.

Bottom line: The Friday weigh-in confirmed the physical setup for the fight. Teixeira’s reported 10-pound weight advantage, paired with both men making their boxing debuts, gives Spaten Fight Night 3 a clear storyline: can UFC championship-caliber experience translate into boxing execution on the sport’s own terms?
