The Portuguese basketball federation said Widemond collapsed in the locker room Sunday during halftime of a game between his team Ovarense and Academica in Leiria, in northern Portugal.

Widemond, a native of Newark, N.J., had played 10 minutes in the third-place playoff game of the cup competition, which was canceled following his death.

“He was sitting on a bench, listening with the others to what the coach was saying, when he just keeled over,” Ovarense sports director Jose Eduardo said.

A doctor immediately began trying to resuscitate Widemond and those efforts continued in an ambulance and then at the hospital, Eduardo told public broadcaster RTP.
