Sky Sports sources understand Portsmouth are close to signing Aston Villa full-back Nicky Shorey on a season-long loan deal.
Shorey has started all five of Villa's games this season, but the recent arrival of Stephen Warnock has raised more uncertainty over his future with Martin O'Neill's side.
The England international joined Villa last summer from Reading, but found himself in and out of O'Neill's side last term.
He was regularly replaced at left-back by Luke Young and recently admitted he was unsure if he would still be at Villa Park by the close of the transfer window.
And though the 28-year-old was prepared to fight for his place following the capture of Warnock, he now looks set for a move to Portsmouth.
Villa have accepted a loan offer from Pompey and Shorey is travelling to Fratton Park to undergo a medical.
Pompey are expected to be among the busiest clubs in the transfer market on the final day of the window and have also agreed a deal with Benfica to sign Hassan Yebda on loan.
