Therry Racon could stay at Portsmouth until January after impressing since returning to the club last month, according to reports.
The midfielder has made five appearances in that time and replaced captain Johnny Ertl in the win against Exeter City at the weekend.
Racon's new deal will also include an option to extend his stay at Fratton Park until the end of the season, according to the Portsmouth News.
Racon made 18 appearances for Pompey last season while on loan from Millwall.
