Doncaster have extended Sam Johnstone's loan spell from Manchester United by a further month.
Johnstone initially joined the Sky Bet Championship club on a month-long deal at the end of January.
The 20-year-old goalkeeper made his debut the next day on February 1 against Middlesbrough at the Keepmoat Stadium and kept a clean sheet in a goalless draw.
He has made five appearances for Doncaster as Ross Turnbull continues to step up his comeback from injury.
