Derby County had to settle for a 1-1 draw with Ipswich Town at the bottom of the table on Wednesday evening at Portman Road.

Tom Lawry's previous strike against his former club put the Rams in the lead, but substitute Jon Nolan stood for the Tractor Boys 10 minutes into the second half.

Both sides could have won it, with derby contested by the woodwork in injury time, but it ended up being anything but square.

While Frank Lampard's men extended their unbeaten run to six games, they missed the chance to return to the play-off zone of the Sky Bet Championship.

They are still seventh in the table, just behind Middlesbrough in goal difference after Tony Pulis' men lost 1-0 at Sheffield United.

Lampard made three changes to the side that started Saturday's 2-0 home win over Hull City.

Andy King made his full debut after borrowing from Leicester City after being out of the bank late against Hull.

There was also a recall for fellow player Bradley Johnson, who made his first appearance since the notorious Stoke game in November. Then he was banned for allegedly biting opponent Joe Allen for five games.

In the meantime, Lawrence returned to the starting grid after missing the hull due to a calf injury.

Tom Huddlestone, Craig Bryson and Florian Jozefzoon were the trailblazers.

Jack Marriott, on the way back from an ankle injury, did not finish the squad.

This meant that Martyn Waghorn – signed by Ipswich in the summer – again led the line and beat his two goals over the weekend.

Ashley Cole rebuilt the bench, with Scott Carson (thigh) and Mason Mount (thigh) still out, along with longtime absentees Marcus Olsson, Craig Forsyth (both knee) and Curtis Davies (Achilles).

Ipswich boss Paul Lambert made four changes to the side that started 3-0 against Norwich City on Sunday.

Myles Kenlock, Flynn Downes, Teddy Bishop and Collin Quaner were all in the starting lineup.

They replaced the injured duo Luke Chambers and Freddie Sears, the sick Cole Skuse and Nolan.

Matthew Pennington, a loan target from Derby last month, started in defense of the home team.

Duane Holmes started right, Lawrence left and Harry Wilson played a central role.

King and Johnson were in a 4-2-3-1 formation ahead of the last four.

Derby was right on the forefoot – taking the lead within two minutes.

Johnson's floated ball into the box was deflected by Jayden Bogle for Lawrence, whose volley shot deflected past Bartosz Bialkowski from 10 yards out.

Lawrence injured himself in the process of the meeting, limping off to celebrate, but it was OK to continue after the treatment.

Fikayo Tomori's slip-up almost struck Will Keane, but the derby defender finally recovered impressively as he is used to it.

Quaner's shot from the edge of the box was deflected to the rear – but the Rams looked relatively unmoved at the opening change.

Waghorn was booked for diving after being challenged by Pennington.

Derby played some nice things without creating any more clear chances.

Holmes saw his shot blocked in the box after a neat build.

Ipswich broke off and Alan Judge fed Quaner, who fired just off the edge of the area.

Moments later, Tomori made an important block when Keane hit the goal.

The game was interrupted when Wilson and Lawrence both had to be treated for thrusts – but both could go on.

Judge's left-footed free-kick from the left was headed forward by Trevoh Chalobah's head, but Kelle Roos watched him leave his distant post.

Derby approached shortly before the break when Lawrence clicked on Wagner's corner from Waghorn and was distracted wide by Tomori from close range.

The Rams had their slim lead in the second half, but Pennington's header after another free kick by Judge reminded them that there was still a lot to do.

James Bree fired a 20-yard shot after Lawrence was accidentally beaten by his team-mate Johnson.

Ipswich equalized in the 55th minute.

Quaner ran for derby defense before finding Nolan at his right. The midfielder had just retired, but made no mistake when he passed a first shot from 15 meters at Roos.

Raised by the gate, the hosts seemed to take the initiative.

Suddenly derby wobbled. Judge's 30-meter free-kick was held well by Roos before Teddy Bishop threw back the effort.

Judges Judge Jonas Knudsen fell in the 68th minute and sent a shot to the top corner just to let the slender Holmes drop the line.

Chalobah shot up as Ipswich raised the pressure – but Derby survived any further damage and came back later in the game.

Scott Malone had blocked a shot before substitute Bryson was close before Bartosz Bialkowski hit the ball easily – but Waghorn was penalized for a foul on the keeper.

In the 84th minute Richard Keogh – still from one corner – came into the back of the head to reach the penalty area at the end of a ball, but his header was parried by Bialkowski and Tomori sent the long shot.

At the other end, Pennington threw Judge's free kick back into the path of substitute Andre Dozzell, whose shot fell on goal but was blocked by Tomori.

Bialkowski was reinstated to tip Waghorn's head after a Lawrence free-kick.

In the first minute of added time, the Rams had almost won.

Lawrence & # 39; s corner from the left came off of the far post from David Nugent, but his header hit the crossbar.

Derby pushed to the end and in the final seconds Nugent dropped the ball eight meters, but he could only hook directly into the goalkeeper in a crowded area.
