The Bengals signed Grandy off the Vikings' practice squad Monday, Aaron Wilson of KPRC 2 Houston reports.
Grandy spent the previous two seasons with Cincinnati prior to being a part of final cuts this past summer. With Tanner Hudson (pectoral) done for the season and Erick All going down with a knee injury Sunday against the Ravens, Grandy gives the Bengals another reliable tight end behind Mike Gesicki and Drew Sample.
