Swindon Town boss Danny Wilson has strengthened his squad by agreeing deals for four players.
Gordon Greer and Hal Robson-Kanu have joined on loan, while Hamdi Razak and Jean-Francois Lescinel have earned deals after impressing on trial.
Wilson has brought Greer in from Doncaster on a month's loan, with the defender having struggled with injuries since moving to the Keepmoat Stadium.
Reading winger Robson-Kanu also joins the Robins for a month and has already enjoyed a spell in League One this season with Southend United.
Striker Razak and defender Lescinel have agreed contracts until the end of the season as revealed by skysports.com last week.
All four players are likely to be in Wilson's squad for Tuesday night's League One encounter at home to Walsall.
