George Thorne has been recalled by West Brom.
Pompey have been dealt a blow heading into the Christmas period with the midfielder heading backing to the Hawthorns.
The Baggies have been hit with injuries, which has seen Roy Hodgson call on the 18-year-old who arrived last month.
Thorne has impressed with Pompey unbeaten in the four games he has played after arriving at the club.
The Chatham-born talent has added a classy, calming influence to the Blues midfield since Michael Appleton tempted him to Fratton Park.
Thorne had indicated he would be happy to remain at Pompey beyond his original loan spell, which ran until January 2, as he picked up valuable playing time.
