The 18-year-old had scans on Monday on the knee he damaged just seconds into Saturday's 1-0 Barclays Premier League defeat at Manchester United. On Monday night, Wickham revealed via Twitter that he had been given a more encouraging prognosis than expected, although he is yet to discover the full extent of the damage.
He tweeted: "Scans showing injury not as bad as first thought, waiting to see a knee specialist later in the week."
The Black Cats have been plagued by serious knee problems in the last 12 months and manager Steve Bruce would be hugely relieved if his ?8.1million summer signing was not sidelined for a significant period.
