Nate Davis cleared waivers today, and the 49ers already have added him to their practice squad. To make room, the 49ers released quarterback Jarrett Brown from the practice squad. We got a strong hint that Davis might clear waivers earlier today when Seattle coach Pete Carroll said the Seahawks were content with their quarterback situation and would not put in a claim for Davis. The Seahawks have just two quarterbacks on the active roster and former 49ers general manager Scot McCloughan, who drafted Davis, has a role in the Seahawks front office.
Mike Singletary has been open in saying he was not happy with Davis' work ethic and that he wanted someone who would put more pressure on No. 2 quarterback David Carr. To that end, the team signed former Ravens quarterback Troy Smith on Monday.
