Adam Shefter broke the news last night.
Washington Head Coach Ron Rivera tells me he has been diagnosed with lymph node cancer after a self check. Rivera shared the news with his team tonight but says the cancer is in the early stages and is considered “very treatable and curable”.

Fortunately it sounds like it was caught in the early stages so a full recovery is expected, though of course it’s cancer so you never know. What is interesting is the mention that it was caught during a ‘self-check’.
