Tyson Williams, the 4-year-old son of Oakland Raiders defensive line coach Terrell Williams, died suddenly on Friday.

The child became ill just over a week ago and passed away Friday night, the Raiders announced.

“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.”

Our thoughts and prayers go out to the Williams family as well.
