Donovan McNabb is stepping away from his NBC sports radio show -- at least temporarily -- to deal with "personal issues" in the wake of his DUI arrest ... TMZ Sports has learned.
McNabb hosts a show called "Under Center" with Mark Malone ... a daily sports talk show on the NBC Sports Radio Network.
But 2 weeks after Donovan's 2nd DUI arrest -- network officials tell us McNabb is taking a break.
"Donovan McNabb is taking immediate leave to address some personal issues, and we support him in this decision," the network tells us.
McNabb WAS on the show yesterday and addressed the arrest -- saying he was "handling the matter." Clearly, he's had a change of heart.
As we previously reported, the former NFL star was arrested for DUI on June 28th in Arizona. It's the 2nd time he's been arrested for DUI in 18 months.
