Pro Football Hall of Famer Randy Moss will leave ESPN’s “NFL Sunday Countdown” for an extended period to focus on a personal health challenge, the network said in a statement Friday.

“(Moss) briefly resigned when he started the show on December 1. For nearly a decade, Randy has been an invaluable member of the team, continually enhancing Countdown with his insight and passion. He has the full support of ESPN and we look forward to welcoming him back when he is ready,” ESPN said in a statement.

Moss, 47, revealed last week that he was battling the illness as he explained why he wears glasses.

“I just want to let the viewers know that me, my wife, my family are fighting inside. I have some great doctors around me. I can’t miss the show. I want to be here with you guys,” Moss said on ESPN’s “NFL Sunday Countdown” last week.

“I feel great. But if you see me with the ‘Michigan turnover glasses’ that I’m wearing, it’s not disrespect because I’m on television. It’s because I’m fighting something. I need all the warriors to pray. God bless you all.” Thank you for the prayers.”

Moss worked through the show with the illness last week, as his ESPN co-hosts Mike Greenberg, Rex Ryan, Alex Smith and Tedy Bruschi wore glasses with him.

“What a great quote,” Greenberg said. “All for one and one for all. If he had worn glasses, we would all be wearing glasses today.”
