Manchester United have suffered a blow as Manucho Goncalves returned to training carrying a foot injury.
The severity of the injury will be confirmed once the Angolan international undergoes a scan.
Initial reports from Goal suggest the striker has become the latest victim of the metatarsal fracture.
Over the past half-dozen seasons Wayne Rooney, Steven Gerrard, David Beckham, Ashley Cole, Ledley King and Michael Owen (amongst others) have all been sidelined with the injury.
If Manucho has a metatarsal problem he will be out of action for eight-ten weeks which will see him miss United's pre-season tour of Africa.
The 25-year-old spent part of last season on loan at Panathinaikos and was expected to be included in the Red Devils squad for their Premier League title defence.
