Dennis Cirkin is still feeling the after-effects of his recent concussion, leading to his absence from the Sunderland squad that travelled to Coventry City yesterday. Cirkin suffered a head injury as he scored Sunderland's equaliser against Millwall at The Den at the beginning of February which kept him out for ten days and saw him miss two games as he followed the concussion protocols, before being eased back into action from the bench against QPR and Bristol City.
