Manchester United reserve goalkeeper Sam Johnstone will stay at Doncaster Rovers until the end of the season.
The 21-year-old shot stopper, who has impressed on loan at the Championship outfit, has featured in 11 games for Paul Dickov's side.
Johnstone has impressed Dickov so much so that he has been keeping 29-year-old Ross Turnbull on the substitutes' bench.
The Englishman is said to be highly-rated by Manchester United's coaching staff but is still someway behind current number one David de Gea.
However Johnstone could be promoted to Manchester United's senior set up next season if either Anders Lindegaard or Ben Amos choose to leave the club.
Reserve team coach Warren Joyce said on Johnstone: "He's had a good bit of experience out on loan and the feedback has been really good from Sam as well.
"It's a good test and a good challenge for him.
"He looks a commanding figure at Championship level and has done really well."
Johnstone will come up against Manchester United trio Tom Thorpe, Tyler Blackett and Federico Macheda at the Keepmoat Stadium on Saturday, as Doncaster Rovers host fellow Championship strugglers Birmingham City.
The Doncaster Rovers custodian will be looking to claim his fifth cleansheet for the South Yorkshire outfit tomorrow.
