Rotherham United have signed duo Kelle Roos and Farrend Rawson on loan from fellow Championship club Derby County.
Goalkeeper Roos, 23, moves to the New York Stadium on a season-long loan, while defender Rawson, 19, joins the Millers on a half-season deal until January 2016.
"Kelle is a talented young goalkeeper with a bright future and I feel he now needs the opportunity to get league games and more experience under his belt," Derby head coach Paul Clement told the Rams' website.
Rawson rejoins Rotherham after having a brief spell with the Millers last season, when he made four appearances.
"His performances during his loan spell last season can only be described as outstanding," Rotherham boss Steve Evans told the club website.
Derby also announced that Roos has also signed a new three-year contract with the Rams.
