NBA Commissioner Adam Silver says the league is researching why Achilles injuries have increased. NEW YORK (AP) – The NBA had already convened a panel of experts to study Achilles tendon injuries even before Indiana star Tyrese Haliburton ruptured his in Game 7 of the NBA Finals, Commissioner Adam Silver said Wednesday night.

Kevin Durant and Tyrese Haliburton entered their respective NBA Finals elimination games with strained right calves. Each wound up leaving early with torn right Achilles tendons.

This season, seven players have suffered torn Achilles tendons, including Indiana's James Wiseman, New Orleans' Dejounte Murray, Indiana's Isaiah Jackson and Miami's Dru Smith, along with the three stars who sustained the injury during the playoffs.
