In Game 7 of this year's NBA Finals, Indiana Pacers guard Tyrese Haliburton tore his Achilles in the first quarter while attempting to drive to the basket on an injured calf. It was the third major Achilles injury of the 2025 NBA playoffs. Curiously, Achilles tears are typically an older-dude injury, as they're most common in middle-aged men, according to a 2018 study published in the Journal of Biomechanics. So the sudden clustering of this injury among star athletes in their prime has inspired a lot of head-scratching among NBA fans and even the league itself. “We had already convened a panel of experts before Tyrese’s most recent Achilles rupture,” NBA commissioner Adam Silver said.

When you zoom out from basketball and consider the broader landscape of sports, the injury surge seems quite real. In baseball, we’ve seen a huge increase in the so-called "Tommy John surgery," which repairs a torn UCL in a pitcher’s elbow. In soccer, ACL injuries have been rising, particularly in women's soccer. And that's before we get to the huge amount of media attention that’s been paid to concussions in football.

What's going on here? Vern Gambetta, a conditioning coach, trainer, and adviser to professional soccer, baseball, basketball, and Olympics teams, explains why major injuries might be surging across sports—and what it tells us about the risks of pushing the human body to its physical limit.
