The Cincinnati Bengals have filled a gap in their tight end room, signing former Minnesota Vikings TE Irv Smith Jr. to a one-year deal.A second-round draft pick out of Alabama, Smith totaled 91 catches for 858 yards and nine touchdowns in his 37 games with Minnesota. He only played in eight games last season, thanks in part to an ankle injury suffered in late October. He was able to come back for the Vikings' Week 18 game against Chicago and also played in their playoff game against the Giants, a 31-24 loss.Smith became an expendable piece of the Vikings' offense after a trade with Detroit to land T.J. Hockenson.As the roster is currently constructed, Smith would slot in as the Bengals' TE1, with the departure of Hayden Hurst who signed a deal earlier this month with the Carolina Panthers, though that could change if the Bengals use an early-round draft pick on a tight end, something early mock drafts have them doing as early as the first round.
