Wolves goalkeeper Wayne Hennessey may have played his last game for the club after being ruled out of action for the rest of the season with a torn cruciate ligament.
Press Association Sport understands Hennessey is set to be sidelined for three to four months, although the bulk of that time will be taken up with the close season.
But Wales number one Hennessey is certain to be one of the players who will attract attention from other clubs should bottom-placed Wolves be relegated from the Barclays Premier League.
He is one of the few players to have enhanced their reputation during a disastrous campaign despite Wolves leaking 73 goals in 34 games.
Hennessey will be unavailable for the final four games in Wolves' uphill battle to avoid the drop after an MRI scan revealed the extent of the damage.
Wolves boss Terry Connor confirmed Hennessey suffered the setback at the Stadium Of Light before the results of the scan came to light.
He said: "Wayne just felt his knee during the game. He went to catch a ball right at the end and didn't think too much of it. But he felt slightly worse on Sunday so the medical guys wanted him to have a scan."
Wolves have now recalled goalkeeper Carl Ikeme from his loan spell at relegated Doncaster following the injury suffered by Hennessey.
Dorus De Vries is set to make his Barclays Premier League debut against Manchester City on Sunday, with Ikeme, who has played 15 times for Doncaster in the Championship this season, providing cover.
Connor told www.wolves.co.uk: "We felt it prudent to recall Carl as a precaution."
