The former Jacksonville Jaguars left tackle ended up spending five days in Mayo Clinic while he fought COVID-19.

About half of his stay was in the ICU, and he said it was shortly after he arrived that he discovered he could be in even deeper trouble.

Boselli, a Pro Football Hall of Fame finalist the past four years, said his oxygen level improved enough over the next 24 hours that he didn’t have to find out what that next level would have been.

That was the beginning of his recovery process, and he improved enough daily that he was discharged Tuesday without needing additional oxygen at home.

The 47-year-old Boselli said he first started feeling ill March 16, but he thought he had a cold or allergies.

Then he felt much worse two days later. That’s also the day he said he got a call and was told he had been around someone who had tested positive for COVID-19.

He called his doctor and got tested that day. Two days later, he received the test results that revealed he had COVID-19.
