Hernes joined United in September 2023 from Shrewsbury Town, where, aged 16, he scored on his professional debut during an EFL Trophy encounter against Wolverhampton Wanderers.

The 19-year-old midfielder, who represents Norway at youth level, was named on the bench for the Magpies' Emirates FA Cup victory against Fulham at Craven Cottage in January 2024 before featuring in a Premier League matchday squad for the first time during Newcastle's 3-1 win against Aston Villa later that month.

Hernes has been a regular fixture for the under-21s so far this term and will now head to the Eredivisie to join a Groningen side currently sitting eighth in the table. Everyone at the club wishes Travis well for his time on loan in the Netherlands.
