Winger Tom Ince, who has not been in this game whatsoever, is replaced by Johnny Russell for Derby, while defender Stephen Warnock also comes off, with Chris Baird coming on.

Things are warming up. There is much more urgency about this game now. Derby have improved but still Sheffield Wednesday look more likely to score first.

Ross Wallace goes in late on Derby's Bradley Johnson and they have a bit of a go at each other but there is nothing serious in that and they calm down. No bookings required.

The ball rolls out to Sheffield Wednesday left-back Daniel Pudil, in acres of space on the edge of the area, but his low shot flies wide. That was a good chance for the hosts.

Derby win a free-kick very close to the edge of the penalty area, slightly left of centre.

Owls boss Carlos Carvalhal shows his skills on the touchline. How long will he wait before making any substitutions? The game could do with an injection of energy.

Derby have their best chance so far, but Bradley Johnson's free header goes over the bar.

That was a good ball into the box from Jacob Butterfield, but the opportunity was wasted.

Neither side made any changes at the break. Will we see a change in the tempo of the game?

Derby were in terrific form heading into this match. Surely they will step things up after the break?

As half-time approaches, can Sheffield Wednesday make the most of their good spell and find the opening goal? Hillsborough is starting to get a bit noisier.

The home side are definitely on top, it has to be said. No goals yet though, and just the one shot on target.

Derby's Chris Martin is almost through on goal at one end, but he can't quite stretch enough to bring the ball down.

At the other end, Fernando Forestieri then immediately wins a corner for Sheffield Wednesday, but the subsequent delivery is too deep to trouble Derby.

Sheffield Wednesday's Ross Wallace receives treatment on the pitch after a tackle from Stephen Warnock, but he is OK to continue.

Former Manchester United and England midfielder Paul Ince is in the crowd at Hillsborough to watch his son Tom in action for the Rams.

Derby's number 23 is yet to really make an impression on this game, but there is plenty of time left.
