Jack Colback has rejoined Sky Bet Championship side Nottingham Forest on a season-long loan from Newcastle.
Sky sources reported last week that Colback was in talks to return to the City Ground after spending the second half of last season at Forest.
Colback made 16 appearances for Aitor Karana's side last term, scoring one goal.
Forest have the option to make the 27-year-old's deal permanent at the end of the season.
"I'm delighted, obviously. It took a bit of time getting it finalised but I'm very pleased to be back," Colback told Forest's website.
"To get promotion is one of the reasons I came back. Also the support of the manager during the off-season. He expressed his feelings about wanting to get me back.
"Obviously when I was here first time around, I enjoyed my time here. A great set of lads and the manager has shown a real ambition to get this club in the Premier League and that is something I want to be part of."
Newcastle-born midfielder Colback is a graduate of the Sunderland academy. He made 135 appearances on Wearside before becoming the first player in more than 15 years to move directly from Sunderland to Newcastle.
Colback is Forest boss Karanka's seventh signing of the summer following the acquisitions of Costel Pantilimon, Jack Robinson, Joao Carvalho, Diogo Goncalves, El Hilal Soudani and Lewis Grabban.
