O'Shea to miss season opener
The versatile Republic of Ireland defender was signed from Manchester United this summer but has made only one appearance in his new club's pre-season campaign, injuring a hamstring on his debut against German side Arminia Bielefeld.
Manager Steve Bruce told the Black Cats' official website, www.safc.com: "We don't think (he will feature) and it would be unwise of me to rush him back."
He continued: "He's close, but he's got a hamstring strain so we have to make sure he's right.
"When he is right and plays we'll be all the better for it because John O'Shea is a big acquisition for this football club."
And Bruce is not ruling out further additions despite wrapping up a deal to make Derry City winger James McClean his 10th signing of a busy summer.
O'Shea and United team-mate Wes Brown joined Birmingham midfielders Craig Gardner and Sebastian Larsson, wingers McClean and David Vaughan, strikers Connor Wickham and Ji Dong-won and Coventry keeper Kieren Westwood in arriving at the Stadium of Light.
A permanent deal was also agreed for former loanee Ahmed Elmohamady.
Bruce said: "The squad size is good at the moment - I'm very pleased with what we've done.
"But as James McClean has shown, a manager's work is never done. If there's someone out there who we feel would be a good addition to the squad then we are in a position to act."
