The eldest son of British rock icon Rod Stewart suffered a devastating defeat in his professional boxing debut, lasting merely 15 seconds before being knocked unconscious at a Misfits Boxing event in Nashville on Saturday evening.
Sean Stewart, 45, faced 27-year-old streaming personality Brendon Davis, known as BDave, in what became the fastest knockout in the promotion's history.
The bout ended abruptly when a powerful right hook connected squarely with Stewart's jaw, sending him crashing to the canvas.
The referee immediately halted the contest as Stewart lay motionless on his back, requiring attention from his corner team whilst his opponent celebrated the swift victory.
Sean Stewart was knocked out within the opening moments of his boxing debut | MISFITSThe encounter began with psychological warfare as BDave entered the ring to the melodies of Rod Stewart's greatest hits, attempting to unsettle his opponent before the opening bell.
Initially, the rock legend's son appeared to seize control, advancing aggressively and landing several combinations that forced the younger fighter to retreat.
However, the momentum shifted dramatically when Stewart inexplicably lowered his defences mid-exchange, apparently attempting to taunt his adversary.
BDave capitalised instantly, delivering a precise overhand right that found its mark.
As Stewart staggered backwards with his arms still lowered, a second devastating blow sent him sprawling to the canvas, ending his professional boxing aspirations in catastrophic fashion.
Throughout the week leading to the bout, Misfits organisers peculiarly identified the fighter as "Rod Stewart's Son" rather than using his given name, a practice that continued even during the live commentary.

|This unusual branding decision proved particularly unfortunate given the humiliating nature of his defeat.
The 80-year-old music legend was notably absent from ringside, having professional commitments in London where he had been performing in recent days.
His absence spared him from witnessing his son's crushing defeat in person, though the viral footage ensured the embarrassing moment would reach audiences far beyond the modest Nashville venue.

Despite claiming to have trained in the sport since childhood, Stewart had been labelled a "gym warrior" by commentator Ben Davis, suggesting his skills were perhaps better suited to practice than actual competition.
The defeat marked BDave's second successive knockout victory, cementing his status as a formidable presence in the influencer boxing circuit.
Following his triumph, the streamer's explicit celebration quickly spread across social media platforms, compounding Stewart's humiliation as the footage went viral.

The 45-year-old musician, who previously described being Rod Stewart's firstborn son as "a curse and a hindrance," discovered that his famous lineage offered no protection from the brutal realities of professional boxing.
