Terrell Owens -- Donovan McNabb Needs Help

Terrell Owens says he's genuinely worried about his ex-teammate Donovan McNabb -- saying he's lucky the QB didn't kill anyone in his recent DUI arrest and wants him to get help, ASAP.

TMZ Sports spoke with T.O. who says the June 28th arrest should serve as a "wake up call" for the former Philadelphia Eagles star.

"DUI is a very serious thing. The number of lives that have been lost from it are staggering. It's a blessing no one was hurt."

Owens continued, "We may not still be playing, but we still serve as role models. You have to be more responsible."
