Newcastle's proposed loan deal for Southampton left-back Matt Targett was called off just hours before the transfer deadline, Sky Sports News understands.
Sky sources reported earlier on Deadline Day that discussions were ongoing over the 21-year-old moving to St James' Park.
Targett is a product of the Saints academy and signed a new five-year deal at St Mary's earlier this month after joining at the age of eight.
A hamstring injury last season meant Targett's playing time was restricted, resulting in just eight appearances.
Targett has represented England at U19 and U21 levels, and was a part of the international team that won the 2016 Toulon tournament.
His Premier League debut came in November 2014 and the full-back went on to make 25 appearances for the club.
