Baron Davis was listed as "questionable" after participating in some of yesterday's practice, but according to Al Iannazzone (and others), there is no longer any question:

No Baron Davis tonight for the Knicks

Not to read into that too much, but I think we're being told that Baron won't play tonight. The question, then, is who will assume Baron's back-up point guard minutes in his second game of absence. Mike Bibby played pretty well during Saturday night's win over the Pacers, and Ian Begley says he'll be the first guy off the bench. Iman Shumpert could play some point as well. As Begley mentions, Toney Douglas is back with the team and, unless Mike Woodson inherited Mike D'Antoni's rotational predilections, could also be a candidate to sop up some of those minutes. In a vacuum, Toney should probably be ahead of Bibby on the depth chart, but Toney certainly hasn't played inside a vacuum this year (he'd be dead if he did, right?), and there's no way of knowing how off his game still is. Of course, once Baron's hamstring gets re-strung, none of this will matter all that much.
