Really sad news. :-( My condolences to his family.
DENVER (AP) -- San Francisco offensive lineman Thomas Herrion collapsed in the locker room and died Sunday morning, shortly after the 49ers played the Denver Broncos in a preseason game. He was 23.
Herrion, a 6-foot-3, 310-pound guard, was on the field for San Francisco's 14-play, 91-yard drive that ended with a touchdown with 2 seconds left.
Players had finished listening to coach Mike Nolan address them in a postgame meeting when Herrion collapsed. Medics administered CPR on him and took him to an ambulance that rushed him to a nearby hospital.
About three hours later, 49ers spokesman Aaron Salkin confirmed that Herrion had been pronounced dead. The cause of death was not immediately known.
