The announcement was made by Stanford University, where McGlockton was in his second season as a defensive assistant. The cause of death was not immediately announced. Funeral arrangements are pending.
McGlockton entered Clemson in 1988 and red-shirted that season. He then played with distinction from 1989-91. The Tigers posted a 29-6-1 for the three years he played, including a 9-2-1 record in 1991 when the Tigers won the ACC Championship.
McGlockton made first-team All-ACC in 1991 and was a freshman All-American in 1989. He tied for the regular season ACC lead in sacks as freshman in 1989 with six, then had a seventh in the bowl victory over West Virginia. He sacked West Virginia quarterback Major Harris, then recovered the ball in the end zone of a touchdown.
The native of Whiteville, NC finished his career with 20.5 sacks, still eighth in Clemson history even though he played just three years. Clemson led the nation in total defense in 1990 and led the nation in rushing defense in 1991 with McGlockton starting on the defensive line. He turned professional after his junior season and was the 16th pick of the April 1992 draft by the Oakland Raiders.
McGlockton's final NFL season was 2003 with the New York Jets. He also played with the Denver Broncos and Kansas Chiefs, as well as the Raiders. He registered 555 tackles, 51 sacks, 14 forced fumbles and four interceptions in his career. He played 12 years and 179 games in his NFL career, the top 10 totals among former Clemson players in the NFL.
He made four straight Pro Bowl trips starting in 1994, when he had a career-high 9½ sacks with three forced fumbles and 48 tackles for the Raiders.
McGlockton had a legendary high school career and was a second-team USA Today All-American at Whiteville High. He still holds the North Carolina Prep record for interception returns for touchdowns in a career with nine.
After turning pro in 1992, he bought shoes and uniforms for the Whiteville basketball team for more than a decade. He also purchased cleats annually for the football team. In 2000, in the twilight of his NFL career, he purchased state championship rings for the entire basketball team and the cheerleaders.
