Pompey have recalled Danny East from his loan spell at Aldershot.
The 23-year-old had agreed to remain at the Shots earlier this week for a third month.
However, an injury to Josh Passley has seen the Blues invoke a clause to immediately recall the versatile performer.
It puts East in the frame for the visit of Luton Town tomorrow, the first time he has been named in a Pompey squad this season.
Adam Webster would be the other contender for the right wing-back role Passley has impressed in during his loan from Fulham.
