Lamar Jackson believes the cramping he suffered during Monday's win at the Cleveland Browns could have been caused by his COVID-19 recovery.

“Probably. Probably because of the body heat and we’re running in the cold,” Jackson said, via Jamison Hensley of ESPN.com. “It was so cold out there. That probably had an effect on that as well. I can’t call it.”

Jackson reiterated that he was “real-life cramping, like my hand, my throwing arm cramping, forearm cramping.”
