Brighton & Hove Albion forward Craig Mackail-Smith has suffered a setback in his recovery from a long-term injury.
The 29-year-old has been out of action since March due to problems with his Achilles and ankle.
Mackail-Smith was expected to be available for selection over the next couple of weeks after making two appearances for Brighton's Under-21 team, but a groin tear has delayed his comeback.
The striker is likely to return to training within a fortnight but a date has not been set for when he will be ready for competitive action.
Brighton continue their bid for a spot in the playoffs against Wigan Athletic on Saturday.
