ALAMEDA, Calif. – The Oakland Raiders organization was deeply saddened Friday night to learn of the tragic passing of Tyson Williams, son of defensive line coach Terrell Williams.

Tyson, who just days ago had celebrated his fourth birthday, acquired a sudden and unexpected illness earlier this month and passed away Friday at Oakland Children’s Hospital after battling more than a week for his precious life.

“We were all shocked by the news we received when we arrived in Baltimore last night,” said Head Coach Dennis Allen. “Terrell and Tifini have been dealing with unimaginable tragedy this week, and our hearts go out to them. We’re all deeply saddened by the passing of Tyson, and our deepest sympathies go out to Terrell and his entire family.”

Born in West Lafayette, Ind., on the day his dad’s Purdue team beat Michigan in Ann Arbor, Nov. 1, 2008, Tyson in four short years had made countless friends in Indiana, Texas and California. He loved cartoons, and his family especially was proud of how caring he was to his eight-month-old brother, Tahj. In fact, before Tyson passed away, he taught his brother to clap.

The Williams family appreciates its privacy during this extremely difficult time. The family will hold a private memorial service this week.

Allen said the defensive coaching staff will share the workload in Williams’ absence, and Williams will have as much time as he needs to mourn with his family before returning to the team.

Those that wish to send condolences should mail them to Williams at team headquarters, 1220 Harbor Bay Parkway; Alameda, CA 94502.
