End to end stuff at the moment.

Jacques Maghoma is set up by Jon Toral with space inside the Wolves box, but he delays as keeper Carl Ikeme rushes out to meet him.

In the end, Maghoma holds onto the ball too long and Conor Coady steals it away.

That's as close as Birmingham have come.

Jonathan Grounds gets past Bjorn Sigurdarson and send a low cross in along the six-yard box.

Clayton Donaldson stretches out to meet it, but he can't direct the ball on target under pressure from Danny Batth.

I suggested a few minutes ago that Gary Rowett might have to make an early change, and now he decides to do so.

Maikel Kieftenbeld is withdrawn, with Jacques Maghoma brought on in his place.

Wolves winger Jeremy Helan, on loan from Sheffield Wednesday, makes a lung-bursting run from inside his own half and gets a shot away.

The Frenchman sees the effort blocked, but it's an encouraging sign for Wolves head coach Kenny Jackett.

Birmingham manager Gary Rowett has stuck with the same team for this half, but he might feel compelled to make a change sooner rather than later. 

Wolves are well on top, but Dominic Iorfa and Conor Coady have both wasted crosses from good positions down the right wing.

Back under way at Molineux, and Michal Zyro has a chance to opening the scoring.

The Wolves forward turns a defender but slices his left-footed shot wide.

Substitute Zyro had only been on the pitch about 20 seconds, having replaced Nathan Byrne at half-time.

There are 45 minutes to go at Molineux - can either Wolves or Birmingham summon up enough quality in front of goal to break the deadlock?

But don't forget, it isn't our only Championship action of the afternoon. We'll also be providing a full text commentary on the match between Charlton Athletic and Middlesbrough at The Valley - that one kicks-off at 15:30 GMT.

If FA Cup action is more your cup of tea, Arsenal and Watford are also goalless in the first of today's sixth round games.

James Gheerbrant is describing all the action, and you can follow along here.

A half of few chances, but Wolves were starting to threaten late on.

Birmingham have yet to produce a single shot on target. 

This is a bit more like it from Wolves, as Dominic Iorfa's cross eventually drops for George Saville just inside the box.

Saville's shot is blocked, though shouts for handball from the crowd are a little optimistic.

The effort did come off a Birmingham defender's arm, but the shot came at him from point-blank range.

Jeremy Helan does well to hold the ball up, before feeding Nathan Byrne down the Wolves right.

Byrne's cross is a good one as well, and Tomasz Kuszczak has to be alert to keep out George Saville's header.

It's all a bit scrappy right now, with Wolves perhaps slightly shading the contest.

The hosts have had plenty of possession, but neither side looks like breaking the deadlock as we close in on half-time.

Birmingham are in the ascendancy, but they might regret not testing Wolves keeper Carl Ikeme.

Dominic Iorfa threatens to punish Blues with a burst forward from right-back, but his shot is deflected high into the air and comfortably dealt with by Tomasz Kuszczak.

Much better from Birmingham, as David Cotterill's deflected cross is inches away from finding Clayton Donaldson.

David Davis then runs from close to the half-way line and gets a shot away, but it's well over the bar.

Almost an opening for Birmingham as Paul Caddis' ball picks out Maikel Kieftenbeld on the edge of the Wolves box. 

The Dutch midfielder's touch is poor in the end, and Wolves clear their lines.

The visitors, who have failed to score on their last three league trips to Molineux, have yet to muster a single shot so far.
