CORVALLIS, Ore. — Oregon State defensive tackle Fred Thompson died Wednesday night after he collapsed while playing basketball at a campus recreation center.

Thompson, just four days shy of his 20th birthday, was taken to Good Samaritan Hospital in Corvallis, where he was pronounced dead.

Thompson, 6-foot-4 and 317 pounds, was a true freshman from Richmond, Calif., who played at Oakland Tech High School.

He was part of the 2010 recruiting class but delayed his enrollment until this January. He spent this season recovering from shoulder surgery and was considered a grayshirt.

Coach Mike Riley was on a recruiting trip, but was expected back at Oregon State on Thursday.
