Willson said he spent time in the hospital during the offseason due to a pericardial effusion. He said the hospitalization changed his “perspective on a lot of things with respect to my life.”
“After reflecting on everything yesterday and being in the building, I have decided that it’s time for me to begin with the next chapter of my life,” Willson wrote.
Willson was a fan favorite and has been a part of the Seahawks in some way for most of his NFL career. Willson was a fifth-round pick by Seattle in 2013 and spent parts of seven seasons with the Seahawks.
