NBA pushes back on study hypothesis linking heavier workloads to uptick in Achilles tears

The NBA is disputing a narrative that has circulated widely in recent months, namely that increased workloads across the league could be contributing to a spike in Achilles tendon tears. In a development reported Aug. 4, the league pushed back on a small study that claimed to find an association between heavier player workloads and the timing of Achilles injuries.

The backdrop is a recent season that appeared to stand out statistically. According to the report, there were seven Achilles tears in the NBA that year, compared with none the season before. The next season, the injuries reportedly fell again to one case, noted in the report as involving Donte DiVincenzo.

The “why now” discussion intensified because several of the injuries occurred in moments that were nationally visible and playoff-relevant. The report points to Tyrese Haliburton’s Achilles injury in Game 7 of the NBA Finals as the most famous example, while also citing Jayson Tatum and Damian Lillard as other prominent names tied to the same broader conversation.

What is at issue is not whether Achilles tendon injuries are a serious concern for players and teams, but whether workload is the most convincing explanation for the cluster. The study the NBA responded to suggested a connection between workload levels and the likelihood or timing of tears, while the league’s pushback indicates it does not accept that conclusion as currently supported.

It is also a reminder that Achilles injuries are relatively rare but high-impact events, and that even when patterns are observable in a small sample, there can be multiple competing explanations. Conditioning methods, recovery protocols, biomechanics, and individual risk factors can all matter, and the timing of injuries during the most visible part of the calendar can shape how quickly narratives take hold.

For teams, the practical takeaway is that Achilles injuries will remain a central focus of medical monitoring and load-management debates, even if the workload-study linkage is contested. The report’s key point is that the league is willing to challenge external analysis rather than simply adopt it, which could affect how publicly discussed prevention strategies are framed moving forward.

What to watch next is whether the NBA offers any additional detail about its response, such as methodological concerns with the study or references to broader datasets and medical perspectives. It will also be important to see whether future research, ideally with larger samples and more robust comparisons, can better separate true causal drivers from correlations that appear in isolated seasons.
