Chester McGlockton, a four-time Pro Bowler for the Los Angeles/Oakland Raiders, died early Wednesday morning of an apparent heart attack.
The 42-year-old McGlockton had spent the past two years as a defensive assistant at Stanford.
Born in Whiteville, N.C., McGlockton was a high school All-American before starring at Clemson for three seasons. He was selected 16th overall in the 1992 NFL draft by the Los Angeles Raiders and would go on to play 12 seasons in the league, making four Pro Bowls and finishing his career with 48.5 sacks.
He retired in 2003 after stints with the Denver Broncos, Kansas City Chiefs and New York Jets. In 2010, McGlockton completed his undergraduate degree at Tennessee-Martin. Later that year, he took a coaching job at Stanford.
"The thoughts and prayers of the Raider Nation are with the McGlockton family during this difficult time,'' Raiders CEO Amy Trask said in a statement.
McGlockton is survived by his wife, Zina, and two children.
