DENVER — Broncos running back Damien Nash collapsed and died after a charity basketball game in suburban St. Louis on Saturday, less than two months after the slaying of teammate Darrent Williams.

“We have been informed of the passing of Damien Nash,” team spokesman Jim Saccomano said Saturday night. “We are attempting to get more details. ... We do know it’s true.”

Officials at Christian Hospital in St. Louis said the 24-year-old Nash died early Saturday evening. The cause of death wasn’t immediately determined.

Nash collapsed shortly after participating in the game benefiting a foundation named for older brother Darris Nash. The foundation raises money for heart transplant research. It was established last month, after Darris Nash received a heart transplant.

Former Missouri receiver Sean Coffey was at the event with Nash and told the St. Louis Post-Dispatch there was no indication anything was wrong.

“Everything was normal. ... We were playing around at the game. ... He was fine,” Coffey told the newspaper. “I give my best to his family. This is crazy. I can’t believe this is happening. It was the first time I had seen him in a couple of years. I can’t believe he’s gone. I’m so happy I got to see him one last time.”

Nash was from East St. Louis, Ill., and played two years at Missouri after playing at Coffeyville Community College in Kansas.

“The Denver Broncos organization is once again struck with profound sadness over the tragic loss of one of our players,” team owner Pat Bowlen said in a statement. “This is a tremendous tragedy and our hearts go out to the entire Nash family.”

The Broncos are still reeling from the slaying of Williams, who was shot once in the neck while leaving a New Year’s Eve party in his rented stretch Hummer in downtown Denver hours after the season ended. His slaying remains unsolved.

A fifth-round draft choice by Tennessee in 2005, Nash played in three games for the Titans. The Broncos signed him as a free agent last season and he played in three games, rushing for 66 yards on 18 carries. In his two-year career, he had 24 carries for 98 yards and seven receptions for 55 yards.
