"I do blame the NFL. I blame the NFL for not holding themselves accountable."
Matt Stafford's wife just went OFF on the NFL over the Lions QB's false-positive COVID-19 test results ... saying the improper diagnosis has made her life a "nightmare" the past few days.
"I have been losing my mind because of how my Family has been treated since my husband was put on COVID-IR," Kelly Stafford said Tuesday.
"Even after we knew it was false positive, our school told us they were not allowed back, I was approached in a grocery store and told I was 'endangering others,' my kids were harassed and kicked off a playground, I was told I needed to wait in my car when trying to pick up food, and people closest to us had to get tested just so they could go back to work .
