The 21-year-old, who made his full Wales debut earlier this season after some impressive performances for the Hatters, has returned to the Premier League side with immediate effect.
Norrington-Davies made 22 appearances during his four-month spell in Bedfordshire, helping the Town to an excellent start in the Championship, a run to the third round of the Carabao Cup and into the FA Cup fourth round.
We thank Rhys for his efforts and wish him well for his future career.
