Portsmouth have confirmed that Scott Allan will remain at Fratton Park for another month.
The West Bromwich Albion midfielder has featured in four games for the League One side since joining on loan last month.
Portsmouth's caretaker boss Guy Whittingham told BBC Radio Solent: "Scott has agreed to sign for another month so that is good news for us. I am pleased to get that done.
"He can be influential has got good ability, can see a pass and unlock defences."
It is the 21-year old's second loan spell at the club, having played 15 games for Portsmouth last season.
