The Bengals signed Hudson off the practice squad to the active roster Tuesday.
Hudson was elevated from the practice squad for two of the Bengals' first three games of the regular season, accumulating three catches on as many targets for 17 yards. He'll now be a part of the team's 53-man roster moving forward and will contribute mostly on special teams and in a depth role on offense behind fellow tight ends Mike Gesicki, Drew Sample and Erick All.
