All 30 NBA teams have been sent subpoenas by Seton Hall as they seek a trove of scouting materials and other documents centered on Myles Powell.

Powell is suing Seton Hall, former basketball coach Kevin Willard and its longtime director of sports medicine Tony Testa for gross negligence over their handling of his injury.

The Memphis Grizzlies filed a motion in federal court seeking to quash or limit the scope of the subpoena to “protect its business interests and confidential trade secrets.”

“There exists no good reason to draw Memphis Basketball into a dispute between Seton Hall and a former NCAA basketball player that involves secret text messages, under-the-table pain narcotic administration, and failure to properly diagnose an injury,” the Grizzlies’ motion states, alluding to the allegations Powell has made against Seton Hall.

Powell originally filed his lawsuit against Seton Hall, Willard and Testa in 2021.

Powell blamed injury management for not being selected in the 2020 NBA draft.

The emerging document dispute calls to mind a similar subpoenaing of NBA teams two years ago by AIG, following a lawsuit filed against the insurance giant by former pro basketball player Chandler Parsons.
