In this second half Boro haven't created the same chances as they did in the first half.

It seems as if they are running out of ideas.

Patrick Agyemang is booked for what looked like dissent after a foul was given.

Kieran McKenna sends on the cavalry for Ipswich.

Chuba Akpom and George Hirst are on for Ivan Azon and Anis Mehmeti.

Not bad replacements when you need a goal.

Patrick Agyemang feeds Joe Ward on the right after a swift move from Derby.

His effort at the near post is a good one, and may even shave the outside of James Beadle's post.

Suddenly this game feels quite finely balanced. Birmingham have come into the game since the changes, but Derby are such a threat at the other end.

Middlesbrough send on some more firepower.

Leo Castledine replaces Luke Ayling as they search for a breakthrough.

Jaden Philogene and Jack Taylor are on.

Millwall send on Barry Bannan for Luke Cundle.

A big 22 minutes remaining.

Sammie Szmodics is inches away from doubling Derby's lead!

He is fed by Ben Brereton Diaz before swivelling on the edge of the area and firing just wide.

Blackburn make a double change.

Moussa Baradji and Yuri Ribeiro are off.

On come Todd Cantwell and Harry Pickering.

Could this be a good point for Rovers or might there be more on offer?

Derby are now making a substitution.

Jaydon Banel comes on for Rhian Brewster, who has been struggling with an injury for the last 10 minutes or so.

Ipswich are getting back on top.

Jack Clarke finds Dan Neil whose shot is deflected inches wide off Billy Mitchell.

A 10th Ipswich corner from which Jacob Greaves goes to ground - shouts for a penalty.

Nothing doing says Michael Salisbury.

The changes have given Birmingham impetus.

Middlesbrough fans have really turned up the noise in the last few minutes and their team needs it.

They have really toiled in the first 15 minutes of this half.

Blackburn are being penned back, but you can sense a bit of anxiety in Boro's play.

A goal feels like it would be absolutely priceless.

Millwall have changed to two up front, and our centre-backs just aren't used to playing against that style. How many teams do you see play like that these days?

The change of system by Alex Neill has definitely worked at half-time for Millwall.

Tommy Conway finds Aidan Morris whose shot is saved by Balazs Toth in the Blackburn goal.

Can they find a way past the Rovers goalkeeper who has done well so far?

Great link-up between Patrick Agyemang and Sammie Szmodics.

Agyeman judges the bounce of a long ball perfectly and heads it onto Szmodics, who shoots tamely at James Beadle's goal.
