Sheffield United have their first sight of goal now. A corner finds centre-back Jack O'Connell, who forces a save from Wolves goalkeeper John Ruddy.

A quiet opening period has livened up a bit at St Andrew's!

After a spell of pressure from Sheffield Wednesday, Harlee Dean clears the danger and the visitors win a corner which Jeremie Boga clears.

Game on!

Wolves have the best chance of the game so far, out of absolutely nothing.

Blades defender Cameron Carter-Vickers slips, allowing Leo Bonatini a shot at goal, but he fires straight at goalkeeper Jamal Blackman.

Jeremie Boga comes close to giving the hosts the lead inside the first 10 minutes but he drives the ball wide of the mark from long range.

A reminder that the winners of the game at Bramall Lane will go second in the Championship. Wolves will go top if they win by three clear goals.

A pretty uneventful start so far.

A couple of Wolves players have signed new four-year contracts in the past week.

Centre-back Conor Coady agreed to extend his stay at Molineux on Friday, and full-back Matt Doherty did followed suit yesterday...

Wolves looked fairly relaxed on arriving at Bramall Lane a little earlier on.

The EFL and Birmingham City say they are working on a resolution after it was confirmed there will be no goal-line technology available for tonight's game against Sheffield Wednesday.

Goal-line technology was introduced for all Championship fixtures at the start of the season, but low floodlight level values at St Andrew's will prevent the system from operating properly.

Plenty of Wolves supporters are becoming tired of onlookers asking: "Yeah, but can they do it on a cold Wednesday night?"

Wanderers - packed with overseas talent - entered the Championship season as one of the great unknowns, but have shown themselves to be genuine promotion contenders by collecting 20 points from their first nine games.

Alfred N'Diaye's stoppage-time winner against Barnsley on Saturday extended their unbeaten run to five league games.

The Senegal midfielder told BBC WM. "We want to go to the Premier League. We have one of the best teams in the Championship. We know that, but that is not enough - we need to fight and work for that goal."

Boyhood Sheffield United fan Chris Wilder got the perfect 50th birthday present as his Blades side won Sunday's Steel City derby at Hillsborough.

"I'm blown away with the occasion because I never got to play in this derby," Wilder told BBC Radio Sheffield. "It was a tremendous occasion and I thought we thoroughly deserved the victory.

"Nobody can tell me this is just another three points because it isn't."

Under new caretaker manager Lee Carsley, Birmingham City ended their six-game losing run with a 1-1 draw at Derby on Saturday.

The boyhood Blues fan will take charge of the team for the first time on home soil tonight.

Carsley told BBC WM: "Saturday was a proud moment. The pressure I feel managing this team is a lot more personal. My family are Blues fans and I'm from the area.

"It's going to be a big moment for myself and my family. Ultimately it doesn't matter about me - it's about making sure the lads perform."

For every success story in a local derby, there's always one of disappointment and frustration.

Sheffield Wednesday boss Carlos Carvalhal accepted responsibility for the Owls' 4-2 home defeat by local rivals Sheffield United.

He told BBC Radio Sheffield: "I don't remember the last time we conceded four goals and we made mistakes I had not seen us make.

"I'm the coach and I'm responsible. We need to react fast because we had been doing well before today."

As we mentioned, Cardiff are three points clear at the top of the Championship after an impressive win over previous leaders Leeds last night...

Birmingham City make one change from the side that drew 1-1 with Derby County on Saturday. Sam Gallagher is replaced by Lukas Jutkiewicz, who scored at Pride Park.

The visitors make three changes to the team that lost 4-2 to rivals Sheffield United on Sunday. Goalkeeper Keiren Westwood misses out with a rib injury and is replaced by Joe Wildsmith, while David Jones and Ross Wallace drop to the bench in place of Jacob Butterfield and Morgan Fox.

Birmingham City: Kuszczak, Nsue, Morrison, Dean, Colin, Davis, Ndoye, Gardner, Maghoma, Boga, Jutkiewicz.

Sheffield Wednesday: Wildsmith, Hunt, van Aken, Lees, Fox, Lee, Butterfield, Bannan, Reach, Fletcher, Hooper.

It's an easy selection for Chris Wilder - the Sheffield United manager names the same starting line-up that beat Sheffield Wednesday on Sunday.

Wolves make three changes to the team that beat Barnsley on Saturday. Left-back Barry Douglas and midfielder Alfred N'Diaye start, as does winger Helder Costa, who hasn't played since 1 April because of an ankle injury which required surgery.

Sheffield United: Blackman, Wright, O'Connell, Carter-Vickers, Baldock, Basham, Fleck, Coutts, Stevens, Brooks, Clarke.

Wolves: Ruddy, Batth, Coady, Miranda, Doherty, Neves, N'Diaye, Douglas, Costa, Bonatini, Jota.

After 10 games of the Championship season, it's Cardiff City who have set the pace.

The Welsh side's 3-1 win over Leeds on Tuesday put them three points clear at the top of the table, but Sheffield United and Wolves will bid to close that gap at Bramall Lane tonight.

Birmingham City are in trouble at the bottom, while Sheffield Wednesday are licking their wounds after losing a big local derby to the Blades on Sunday.

Welcome to BBC Sport's live text coverage of tonight's two Championship matches. Good to have you with us.
