Everton staff delighted with McFadden return
"He was terrific," Irvine told evertonfc.com.
"In actual fact, we were toying with the idea of not playing him and instead leaving him to play some of the game against Warrington on Thursday.
"Faddy was a bit disappointed when he thought he might not be involved. But we talked it through, spoke to Baz and we decided it would be okay.
"The last thing we want is for him to break down again. It has happened once before and if it happens again, he is back to square one. We obviously can't afford that."
