A foot injury ruled the Fulham striker out of Alex's impressive 3-1 win at Preston last time out.
But Davis is delighted to have him back in contention and on board until the new year after he netted four goals during his first month at Gresty Road,
Davis said: "He's done well, four goals in seven games. He was injured for the Preston game, he would have started.
"He's got a hole in his foot, like a puncture wound from a stud which he picked up. He's had three stitches from that.
"We worried about infection and all the rest of it and he's obviously not our player so we didn't want to risk that.
"He'll be okay. He'll be training on Thursday and will be fine for Saturday.
"I spoke to him a couple of days ago, sat him down and said 'We're keen to keep you, do you want to stay?'.
"He's keen to stay, delighted to stay and he's enjoyed himself."
