The 49ers signed Rucci to a reserve/future contract Thursday.
Rucci joined the 49ers' practice squad Jan. 14 but wasn't elevated to the active roster for the NFC divisional-round game against the Seahawks despite the absence of George Kittle (Achilles). Rucci will be on the 49ers' 90-man roster when the offseason officially begins Feb. 9, giving him the opportunity to participate in OTAs and minicamp.
