Aug. 21 (UPI) — Washington Football Team coach Ron Rivera has been diagnosed with skin cancer.

Rivera, 58, announced his squamous cell carcinoma diagnosis Thursday after he detected it during a self-care check. Washington said the cancer is in an early stage and is considered very treatable and curable.”

Squamous cell carcinoma is a common form of skin cancer, which develops in the squamous cells located in the middle and outer layers of skin. It is usually not life threatening, but can be aggressive.

“Stephanie, Christopher, Courtney [Rivera’s wife, son and daughter] and I thank you all for your love and support,” Rivera tweeted Thursday.

The veteran coach has consulted with oncology specialists, the team’s medical staff and other doctors to establish a treatment plan. Rivera met with reporters Thursday, but did not speak about the diagnosis.

“For now, coach has asked that the team keep things business as usual and remain focused, but a ‘Plan B’ is in place if it is determined that he should take some time off,” Washington said.

Many coaches, players and teams around the NFL posted messages of support for Rivera Thursday on social media.
