Sunderland could be without Argentinian star Julio Arca for their trip to Bolton at the weekend.
The 25-year-old injured his hamstring during caretaker-manager Kevin Ball's first game in charge, a 1-0 defeat at home to Wigan, and is struggling to be fit for the match at The Reebok Stadium.
"He's a doubt and we'll just have to wait and find out how he is later in the week," said Ball.
The injury to Arca has forced Sunderland to recall youngster Dan Smith from his loan spell at Huddersfield.
Smith has impressed since joining The Terriers in January and could now get his chance to show his qualities in The Premiership.
