NFL agent Buddy Baker -- who's repped stars like Doug Baldwin and Jack Doyle -- lost both his parents to COVID-19 on Sunday ... and now, he's begging the public to help stop others from suffering the same fate.
Baker posted an emotional video Tuesday explaining the tragic news ... saying both his mom and dad were in "perfect health" just a few weeks ago.
Sadly, he says both contracted coronavirus ... and the two -- who were married for 51 years -- died from complications of the disease just six minutes apart on Sunday.
