Gillingham boss Mark Stimson fears on-loan striker Febian Brandy could be sidelined for up to four weeks through injury.
Brandy picked up a knock during the midweek defeat at Leyton Orient and he missed Saturday's 0-0 draw against Carlisle United.
He is now set for a spell on the sidelines, with Stimson feeling the Manchester United youngster was missed in the stalemate with Carlisle.
"We missed Febian out there and you could see him causing the Carlisle centre-backs problems," said Stimson.
"But we are paying the price for Tuesday's game. We didn't get enough time to warm up at Leyton Orient and he now has a tear and could be out for anything between two and four weeks."
Brandy has scored once in six appearances for the Gills since joining on a three-month loan deal from United in early November.
