Wednesday’s new centre half Oguchi Onyewu cannot play in the FA Cup replay against Macclesfield on Tuesday.
To be eligible for a Cup replay, players have to have been registered with a club at the time of the first meeting between the teams.
But the Owls have achieved their aim of boosting their centre-half department and Onyewu will be in the squad for Saturday’s game at Burnley.
A 31-year-old USA international, he has been signed for the rest of the season and was a free agent after leaving QPR.
The London club took him in October on a short-term deal.
His previous clubs include Standard Liege, Malaga, Sporting Lisbon, Twente and Milan, and he had a spell on loan at Newcastle in 2007.
