Middlesbrough defender Robert Huth is to see a specialist on Monday over his ankle injury.
The 24-year-old Germany international missed his first Barclays Premier League game of the season at Wigan last week with ligament damage, and the Teessiders are seeking expert help as they attempt to assess the extent of the problem.
Manager Gareth Southgate said: "Robert is going to see a specialist on Monday, and the situation will be clearer after that. All we know at the moment is that he has damaged his ankle ligaments."
Huth arrived at Boro in a £6million move from Stamford Bridge in August 2006 after initially failing a medical and then undergoing surgery to address an ankle problem.
He returned to full fitness, only to be struck down by a stress fracture of the foot.
The Berlin-born defender, however, proved both his fitness and his ability last season to the extent that Southgate was prepared to allow Jonathan Woodgate to leave for Tottenham in January.
His latest fitness problem is a concern for the manager, although the fact that it is not connected to the troublesome foot injury is at least some comfort.
Huth is not the only Boro man currently awaiting injury news with midfielder Julio Arca back in Argentina to consult a specialist over his ankle problem.
The former Sunderland player was forced to put his comeback on hold after breaking down in training, and the Teessiders have allowed him to travel back to South America to see the surgeon who dealt with his knee injury last season.
Southgate said: "Julio is still in Argentina and we are going to asses him further in the middle of next week."
