Harris (thigh) was present for practice Wednesday, Zack Cox of NESN.com reports.
Harris has missed two straight games, but his presence at practice Wednesday suggests that he could return to action Sunday against the Raiders. The Patriots will release their first Week 15 injury report later Wednesday, when the extent of Harris' practice participation will be known. If available this weekend, Harris could fill a leading role out of the backfield, as Rhamondre Stevenson is dealing with an ankle issue and uncertain to play.
