The Saints signed Krull to a reserve/future contract Monday.
Krull signed with the Saints as an undrafted free agent in May and joined the team's practice squad after failing to make the initial 53-man roster. He drew one elevation and made his NFL debut in Week 13, but he didn't record any counting stats across nine offensive snaps. With his new contract, Krull will have a chance to compete for a roster spot during offseason work.
