Mike Williamson out for Wolves' season

The 32-year-old centre half - yet to feature for the club since joining for £200,000 in January - has been ruled out for the remainder of the season.

Williamson arrived from Newcastle with a hamstring injury, which has now cleared up, but further complications around a tendon problem have left the experienced defender unable to reach full fitness.

Wolves have taken the decision to rule Williamson out of their final four games and concentrate on getting him ready for the start of pre-season.

Jackett said Williamson's signing was intended to replace the experience lost when popular centre Richard Stearman joined Fulham at the end of August.

But as so often this season, injuries have ruined Jackett's plan.

The Wolves boss said: "We decided on Monday morning that there wasn't enough time left between now and the end of the season.

"It's a niggling injury. It's the other side of his body to the one he injured at Newcastle. It's frustrating for him and us.

"It's been two separate injuries with the hamstring and the tendon, but it's a long period out and we're very frustrated.

"If you're looking at our centre back options we have needed some experience in there since Richard Stearman has gone.

"We felt Mike could provide us that. Having said that there have been positive performances (at centre half) in Danny Batth, Kortney Hause, Ethan Ebanks-Landell and on Friday Dominic Iorfa.

"We're competitive in that area, but at different times the side has needed some experience."

Williamson made five appearances on loan at Molineux earlier on in the season.

He signed an 18-month contract when moving from St James' Park.
