Baltimore Ravens wide receiver John Brown explained it was a cyst on his spine and not the fact he is carrying a sickle cell trait that impacted his health during the 2016 season.
"I'm healthy. I'm feeling good," Brown said, per Jamison Hensley of ESPN.com. "Sickle cell was never part of the problem."
Hensley noted Brown was diagnosed with the sickle cell trait in October 2016 during his time with the Arizona Cardinals when he was experiencing sore hamstrings. While those with sickle cell trait can experience muscle issues, the receiver pointed to the cyst that was drained following the 2016 campaign.
