Damien Duff could miss the Republic of Ireland's World Cup play-off after suffering a recurrence of his hamstring injury.
Duff had been pencilled in by Blackburn to make his comeback against Leicester at Ewood Park on Monday.
But the left winger has suffered a setback in training and his return has been put back by a week.
According to Rovers' timetable, Duff should still be available for the Republic's two games against either Iran or the United Arab Emirates next month.
However, assistant manager Tony Parkes claimed Duff would not be travelling with the Irish squad if he is not fit to face Southampton next Saturday.
Duff claims the setback should only delay his return by a few days.
"I pulled up in training with a twinge and when I had a scan done yesterday it showed a bit of fluid on the injury," he said. "That has put me back a few days and I just hope it is not too long".
"I'm desperate to play in the play-offs as they are the biggest games for the country in years. It's a couple of weeks until the first leg play-off so I hope I will be ready"./
