Oregon State football player Fred Thompson collapsed and died Wednesday night while playing basketball at a campus gym, the school reported.
Thompson, a freshman from Richmond, California, was pronounced dead after being transported to Good Samaritan Hospital in Corvallis, the school said on its website.
The 6-foot-4, 317 pound defensive tackle died just four days short of his 20th birthday.
The university plans a press conference Thursday to discuss the case, according to the school's website.
Thursday morning, the website showed a picture of Thompson with the words "the thoughts and prayers of Beaver Nation are with Fred's family."
