Pompey have completed the signing of striker Jordy Hiwula on a short-term contract until January 20.
The 26-year-old – who left Coventry at the end of last season – will wear the number 26 shirt during his time at Fratton Park.
Blues assistant manager Joe Gallen said: “We know Jordy well from having scored a couple of goals against us in recent seasons.
“He’s a technical player and also a very good finisher, who has done well in this division in the recent past.
"Jordy adds competition to an already decent frontline and will hopefully have a successful time here with us."
“Speed and brains together is a great combination and he can sense where the space is. Once he gets there, he’s got a real eye for a goal.

Hiwula has spent the past two seasons at Coventry, helping them claim the League One title last term.
A former England under-19 international, he progressed through the ranks at Manchester City before signing for Huddersfield.
Hiwula had several loan spells during his time with the Terriers, most notably at Bradford and Fleetwood.
He could now make his Blues debut against Sunderland in Saturday’s League One clash at the Stadium of Light.
