George Cox has completed a permanent move to Fortuna Sittard, pending international clearance.
The 22-year-old full-back initially joined the top-flight Dutch club last September on loan.
He made 27 appearances in the Eredivisie and scored his first goal against PEC Zwolle in a 1-1 draw in March, in Fortuna’s last game before the season was curtailed because of the Covid-19 crisis.
Cox played for Albion’s under-23s and in the EFL Trophy before a loan spell with Northampton in 2019.
Technical Director Dan Ashworth said: “George has enjoyed playing for Fortuna, and he and the club were keen to make the move permanent.
“This represents a great opportunity for him and it is one he has worked very hard to achieve.
“On behalf of everyone at the club, we wish him every success for his future career and I would like thank him for his efforts during his time with us.”
