Why Errol Spence's Fall Exposes the Danger of Staying Too Long

Errol Spence Jr. announced his retirement in July 2026 following a one-sided unanimous decision loss to Tim Tszyu, closing the book on a career that peaked with an undisputed welterweight championship run but ended with three years of diminishing returns. The Tszyu fight — a bout Spence entered as a former champion trying to reclaim relevance at junior middleweight — laid bare a brutal reality of prizefighting: the margin between elite and shot is thinner than most fighters admit, and crossing back is nearly impossible.

Spence's troubles didn't start with Tszyu. The cracks appeared in his July 2023 loss to Terence Crawford, a fight that exposed slippage in the defensive reflexes that once made him untouchable. He was down three times, outclassed over twelve rounds, and stripped of his welterweight titles in a performance that felt like the end. But instead of stepping away, Spence moved up to 154 pounds — a weight class where his speed advantage evaporated and his power didn't translate. The move made sense on paper; plenty of welterweights have thrived at junior middle. For Spence, it became a slow-motion exit.

What makes Spence's decline instructive is how predictable it was. He'd survived a horrific 2019 car accident that could have ended his career, returning to decision Michael Garcia in December 2020. That fight, a careful points win over a game but limited opponent, hinted at diminished explosion. Then came Yordenis Ugas in April 2022 — another decision, this time with a torn retina that required surgery and kept him out for fifteen months. By the time Crawford dismantled him, Spence had fought twice in three years, both times looking a step slower. The Tszyu loss was the inevitable conclusion to a slide that began the moment he chose activity over preservation.

Boxing history is littered with fighters who stayed too long, but Spence's case underscores a modern wrinkle: the financial pressure to chase legacy fights into your late thirties. At 36, Spence was still a name, still a draw, still capable of landing a big-money opponent like Tszyu. But capability and competitiveness aren't the same thing. The version of Spence who unified three welterweight titles between 2019 and 2022 would have made Tszyu work for every round. The 2026 model couldn't pull the trigger fast enough to trouble a younger, fresher fighter.

The lesson isn't that Spence should have retired after Crawford — though that would have preserved his reputation as one of the best welterweights of his generation. It's that once the reflexes start to fade, no amount of ring IQ or conditioning can compensate. Spence's jab, once a piston that controlled range, became a feeler. His body attack, the foundation of his offense, lost its sting. The car crash, the eye injury, the layoffs — each took a piece. By the time he faced Tszyu, there wasn't enough left to compete at the level he demanded of himself.

Spence retires with a legacy intact but tarnished: a unified champion whose final chapter reads like a warning label. If the Crawford loss was the signal, the Tszyu fight was the confirmation. In boxing, knowing when to leave is as important as knowing when to stay. Spence stayed three years too long, and the sport made him pay for it.
