Sky Sports understands Portsmouth are set to sign former Charlton defender Sam Sodje on a short-term deal.
Sodje is available on a free transfer having been without a club since leaving Notts County last summer.
League One strugglers Portsmouth are desperate to bring in some new faces with Guy Whittingham only having 14 players in his first-team squad.
Sodje has been training with Charlton and Dagenham & Redbridge to maintain his fitness and he is set to go straight into the Portsmouth side.
Portsmouth find themselves in the relegation zone, having not won any of their last 14 matches and face a 10-point penalty if and when they come out of administration.
