Henry (knee) wasn't on the field for Wednesday's practice, Evan Lazar of the Patriots' official site reports.
Henry sustained a knee injury in this past Sunday's 27-17 loss to the Chiefs, leaving the game after compiling 66 yards and a touchdown on seven catches. The tight end has scored in both of his last two games, so the Patriots would be without a key offensive player if he's unable to play Sunday against the Broncos. Henry could still bolster his chances of playing this weekend by returning to practice Thursday or Friday.
