Marc McNulty has left Bramall Lane temporarily to join Bradford City on a season-long loan deal.
The 23-year-old, who spent much of last season on-loan in League Two with Portsmouth, has made two substitute appearances this term against Crewe Alexandra and Millwall.
In total, the Scottish marksman scored 14 times in 53 appearances for the Blades. He links up with Bradford ahead of their fixture at Millwall on Saturday.
The move was allowed to go through after Caolan Lavery boosted Chris Wilder's attacking options at Bramall Lane.
