Pro Football Hall of Famer Randy Moss is stepping away from ESPN's "Sunday NFL Countdown" for an extended time to focus on a personal health challenge, the network said in a statement on Friday. 

"(Moss) briefly addressed the matter at the start of the show on Dec. 1. For nearly a decade, Randy has been an invaluable member of the team, consistently elevating Countdown with his insight and passion. He has ESPN’s full support, and we look forward to welcoming back when he is ready," ESPN’s statement said. 

Moss, 47, revealed last week that he was battling an illness as he addressed why he was wearing glasses.

"I just wanted to let the viewers know that me and my wife and my family are battling something internally. I have some great doctors around me. I couldn’t miss the show. I wanted to be here with you guys," Moss said during last week's ESPN’s "Sunday NFL Countdown."

"I feel great. But if you see me with these ‘Michigan turnover glasses’ that I have on, it’s not being disrespectful because I’m on television. It’s because I’m battling something. I need all the prayer warriors. God bless you all. Thanks for the prayers."

The former Minnesota Vikings and New England Patriots star wide receiver did not say what he was specifically dealing with. 

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. 

"It’s beautifully said. All for one and one for all. If he’s wearing glasses, we’re all wearing glasses today," Greenberg said.

Moss played 14 seasons in the NFL and is second in the Vikings' all-time receiving yards with 9,316 yards.

The six-time Pro Bowler and four-time All-Pro will turn 48 in February.
