The 22-year-old made the most of an offer to train with the Blues by impressing the Fratton Park coaching staff sufficiently enough to be rewarded with a deal until mid-January.
Pompey turned to the player after learning that Tino Anjorin will likely be out until the new year with a hamstring injury. His signing also comes at a time when Anthony Scully continues his rehab after knee surgery.
At present, attack-minded duo Scully and Anjorin are joined in the Blues treatment room by Regan Poole, Connor Ogilvie and Josh Dockerill.
Marlon Pack and Tom Lowery are closing in on their returns to first-team action. But if Pompey are prepared to delve into the free agents market to help maintain their lead at the top of League One, it begs the question – what other freebees are waiting to be snapped up if the need arose again?
Here’s 12 current out-of-work footballers who are no doubt waiting for the phone to ring to be invited back to the game.
