Sunderland midfielder Lee Cattermole will see a specialist later this week amid fears he could be sidelined for months.
The 21-year-old was carried off with a knee injury during Saturday's 1-0 Barclays Premier League victory over Liverpool and the early indications are he suffered ligament damage. Tests later this week will determine the extent of the injury, and whether or not it is the medial or cruciate ligament which has been affected.
The latter is the more serious, and that could see the former Middlesbrough and Wigan man sidelined until well into the new year.
Manager Steve Bruce will keep his fingers cross over his £6million summer signing, who has been a big hit since his move to Wearside.
However, Bruce has at least had better news of striker Kenwyne Jones, who was also carried from the field on a stretcher at the weekend.
The 25-year-old Trinidad and Tobago international was taken straight to hospital after twisting an ankle, but was released and unlike Cattermole, has a chance of making Saturday's trip to Birmingham.
