Browns quarterback Case Keenum has managed to maintain his sense of humor during the coronavirus epidemic.

During a conference call on Wednesday, he invoked Uncle Rico from the comedy “Napoleon Dynamite” to describe his new training regimen.

“Is that the guy that set up the video camera out by his camper and threw the football around in this backyard?’’ Keenum asked. “If you haven’t seen it, you need to go check out the video clip. I feel like Uncle Rico at times in my backyard doing drops and throwing the ball by myself (laughter). I definitely haven’t thrown as much this offseason as I normally have.’’
