DETROIT — The mother of a G League basketball player who died in March after collapsing on the court during a game has filed a federal lawsuit accusing the NBA and Detroit Pistons of negligence.

Zeke Upshaw played for the Grand Rapids Drive, a G League affiliate of the Pistons. He collapsed during a game March 24 and died two days later.

The lawsuit was filed Wednesday in U.S. District Court for the Southern District of New York. The NBA and Pistons are named as defendants, along with SSJ Group and The DeltaPlex Arena.

The lawsuit alleges that medical personnel at the game failed to attempt lifesaving measures in a timely fashion.

“Remarkably, for much longer than four full minutes, no cardio-pulmonary resuscitation (CPR) was initiated, no chest compressions were started, no oxygen mask was placed on his nose and mouth, no airway was cleared and secured, and no defibrillator sensors and electric delivery patches were attached and secured to Zeke’s chest,” the suit says.
