The free-agent running back market has been slow to develop and Michael Bush has been a part of that unexpected lag.

But interest in the Raiders running back's services has been picking up. ESPN’s Adam Schefter is reporting Bush will visit the Seattle Seahawks on Tuesday. In Seattle, he’d be reunited with former Oakland head coach Tom Cable and former Raiders tight end Zach Miller.

Bush has already visited the Bears (where former Oakland starting quarterback Jason Campbell recently signed) and he is supposed to visit Cincinnati Monday. Former Oakland head coach Hue Jackson is on the Bengals’ staff.

At this point, it seems like Bush will not get a contract to start. Because of that, you would think he would consider remaining in Oakland as Darren McFadden’s partner. But because the Raiders have some cap restrictions and other needs (they are still hunting for several cornerbacks, including Shawntae Spencer and Tracy Porter), re-signing Bush right now may not be a top priority.

But if the market for Bush cools down, perhaps a return to Oakland would become more realistic.
