The 20-year old Irishman spent last season at KC Stadium under Steve Bruce and has now been re-signed by the Tigers on a one-month emergency loan.
Brady netted three goals in 41 appearances for Hull last term and could add to that when Wolves come to town tonight.
“The Tigers have signed Robbie Brady from Manchester United on an emergency loan deal,” read a statement on Hull’s official website.
“Since returning to Old Trafford, the left-sided player has featured for Manchester United in the League Cup and progressed to the senior Republic of Ireland squad, playing in the recent World Cup Qualifiers against Germany and Faroe Islands.
“Brady has signed in time to feature in tonight’s home game against Wolverhampton Wanderers.”
