Alex Neil is planning to assess Thorben Hoffmann today before deciding whether he is ready to be involved against MK Dons tomorrow.
On-loan Bayern Munich goalkeeper Hoffmann has missed Sunderland's last two games against Cheltenham and AFC Wimbledon due to illness and he returned to his native Germany to undergo blood tests.
But the tests have come back clear and he returned to Wearside this week and has taken part in training at the Academy of Light.
