Former Red Sox pitcher Jeff Plympton is in need of a kidney donor.
In October, Plympton posted on social media that he has a hereditary condition called Polycystic Kidney Disease (PKD), which he has known for many years. People with this disease develop cysts in their kidneys over time, which prevents them from filtering out waste from blood.
According to the National Kidney Foundation (NKF), about 50 percent of people with PKD will develop kidney failure before their 60th birthday.
