Rovers have extended the loan of goalkeeper Sam Johnstone until the end of the month.
A deal has been reached with Johnstone’s parent club Manchester United to hold the England U21 keeper at the Keepmoat until January 28.
The 21-year-old has made 13 appearances for Rovers during his current spell, conceding just ten goals.
His latest deal will see him available for Rovers’ next five games.
Johnstone was on loan at the Keepmoat for four months last term, making 18 appearances.
He is one year into a three and a half year deal at Old Trafford.
