Matt Targett completed a medical on Wednesday afternoon, ahead of a permanent move to Newcastle, Sky Sports News understands.
Targett enjoyed a hugely successful loan spell on Tyneside last season where he impressed Eddie Howe and the club's new owners.
The 26-year-old played every minute of the 16 Premier League matches he played after joining on January 31, helping to steer the club away from the relegation picture and finish 11th, with five clean sheets kept along the way.
Newcastle have a deal in place to make the move permanent for £15m, which includes £3m loan fee for last season, and are expected to do so in the coming days.
Following the Magpies' 2-0 win over Arsenal on May 16, the former England U21 international appeared to express his interest in joining the club on a permanent, when he spoke to NUTV.
He said: "I think everyone knows what I want, but it's up to the club. It's a massive project, an exciting project, and I'm sure everyone wants to be a part of it.
"I've loved every single minute of my time here. It's been an incredible place to play my football. I've loved every second of it."
