Crofts scored in the 1-1 draw at Nottingham Forest two weeks ago but subsequently pulled out of the Wales squad for last week's Euro 2012 qualifying match in Montenegro because of an ankle injury.
But manager Paul Lambert said: "He's fine. He had a knock on his ankle in the last home game against Swansea but he's okay.
"I left it to him, I wouldn't curtail anyone's chances of playing for the national team. It's a great honour to do it but his ankle flared up after the Forest game."
Former Gillingham striker Simeon Jackson is available despite only returning from international duty with Canada on Thursday but Michael Nelson is sidelined for two months with an ankle injury.
Full-back Steven Smith is yet to make his debut since suffering an ankle injury in pre-season and Zak Whitbread is still out with a calf injury.
