ESPN's Adam Schefter reports the Vikings are set to release QB Donovan McNabb on Thursday. We've seen speculation on this ever since the Broncos granted Kyle Orton his release. McNabb will be subject to the waivers process with $1.5 million remaining on his 2011 salary. He would certainly have interest in playing for his hometown Bears, who have a higher waiver claim than the Texans. We're not sure he'd be much of an upgrade on Caleb Hanie, however.
