According to Shams Charania of The Athletic, Smart will donate his plasma to the National COVID-19 Convalescent Plasma Project, founded by Johns Hopkins immunologist Arturo Casadevall, who brought together experts to form a national network that connects donors, patients, and their doctors. 

Last week, the Federal Drug Administration authorized drug use of convalescent COVID-19 plasma for patients infected with the virus that has swept the world and led to the pandemic.
