Stoke City have extended the loan deal of Portsmouth defender Andy Griffin into a second month.
Griffin, 27, has made five appearances for the Potters, having arrived at the Britannia Stadium just before the transfer window closed last month.
City boss Pulis said: "We've spoken to Portsmouth and that's been done."
Griffin played 21 games for Pompey in the Premiership last season but has hardly featured since Harry Redknapp returned as manager.
