Head coach Mike Vrabel said Henderson (ankle) will "do some more" at Wednesday's practice, Mark Daniels of MassLive.com reports.
Prior to sitting out the Patriots' Week 1 loss at Seattle, Henderson had been sidelined from practice since Aug. 24. The team held an unofficial session Monday, for which Henderson's activity level wasn't divulged, so how he's listed Wednesday may provide insight into his odds to suit up Sunday against the Steelers.
