Carroll looks certain to be rested and is unlikely to play against Man Utd reserves due to the Toon young gun's involvement with the England Under-19s, for whom he bagged the killer goal during a 3-1 win over Russia in Milton Keynes last night in front of 8,814 people.
Sadler's team are currently on a four-game unbeaten run and have the Northumberland Senior Cup final at the end of the season still to look forward to.
Sadler: "We aim to finish the season on a high.
"We have impressed in recent games and we have two great games against Manchester United to finish off the season with before the Northumberland Senior Cup final."
Reserve team striker Carroll's goal for England Under-19s came on 64 minutes to put the lid on things at Milton Keynes after he latched on to a Jack Cork pass to seal victory.
