Crystal Palace 0, Wolves 1: Full Time Report
The visitors almost shot themselves in the foot as the interval approached when Jody Craddock sliced Sean Scannell's cross towards his own net, but the ball spun clear.
Palace came even closer shortly after the break when Ifill's low free-kick from 25 yards fizzed through the wall and was finger-tipped onto the post by Wayne Hennessey at full stretch.
Another defensive mix-up, this time between Craddock and Hennessey, almost gave Ifill a clear run on goal but the Wolves keeper recovered in time.
And Wolves finally made the breakthrough in the 74th minute when Hill was adjudged to have hauled down Kightly and Ebanks-Blake made no mistake for his 22nd goal of the season.
They should have gone further ahead before full-time but George Friend could not convert Ebanks-Blake's cross at the far post.
