The Minnesota Vikings have signed fullback Ryan D'Imperio from their practice squad.
The Vikings announced the move Tuesday and waived tight end Allen Reisner to make room on the roster.
D'Imperio is in his second season out of Rutgers. He was a linebacker in college but has been converted to fullback by the Vikings. The transition has taken some time, and D'Imperio often looked raw and unsure of himself in the role during the preseason.
Tight end Jim Kleinsasser has been getting the bulk of the playing time as Adrian Peterson's lead blocker. D'Imperio could spell him on occasion and contribute on special teams if he is activated.
The Vikings (0-4) host Arizona (1-3) on Sunday.
