Kevin Mbabu has return to his native Switzerland to join BSC Young Boys on a season-long loan deal from Newcastle.
The 21-year-old full-back, who signed a two-year contract extension earlier this summer, made his Premier League debut in a 2-2 draw with Chelsea in September last year.
Mbabu, who joined the Magpies from Servette in January 2013, has five senior appearances to his name.

Meanwhile, Newcastle are among the clubs reportedly interested in Everton midfielder James McCarthy, who has fallen out of favour under Ronald Koeman at Goodison Park.
