The pair played out a 0-0 draw at the City Ground, which Derby ended with 10 men after their Nottingham born midfielder, Tom Huddlestone, was sent off for two bookable offences nine minutes from time.
Afterwards, Keogh criticised the decision to show Huddlestone a second yellow card, and accused Forest's players of 'going down quite easily all game'.
It's fair to say that a number of Nottingham Forest supporters think the Derby defender's comments were a little bit rich coming from him.
Here's what they're saying on Twitter...
Loving Keogh crying over Sunday game.The prat has a nerve to say #nffc players go down to easy.— Mark Cook (@MCookie1986) 13 March 2018
If I looked like Richard Keogh I wouldn't be happy either!— Byron (@ByronSeigneur) 13 March 2018
He is one of the biggest divers in the league. Has been for many a year but its no surprise that he's moaning about other players as that's all he does. #Potkettle.— Jeff (@Jeffwood7) 13 March 2018
Don’t cry mate— Dan (@dankjsmith) 13 March 2018
He dived to gain a free kick that bounced of the wall for a corner. Then saw him smirk about it as he walked to the flag.— Maxwell Mullins (@maxwellgrad) 12 March 2018
He's got a short memory of himself going to ground a few years ago to get Dexter Blackstock sent off— siforest65 (@siforest65) 13 March 2018
In his post match interview he only had praise for Pantilimon, no mention, at all, of Forest players chucking themselves down. Could someone afraid of their job security have had a word with him?— OverFifty_Red_Dog (@eyupmeduck_NFFC) 13 March 2018
A bit rich coming from someone who played with Chris Martin all those years— Chris Pearson (@ChrisPe95168251) 13 March 2018
In fairness its Keogh, he's about as sharp as a wax crayon— Kevin Malpass (@Kwm59Kevin) 12 March 2018
Oh poor boy don't cry about it just like our players didn't when they were being persistently shoved off the ball granted the sending off was a soft one but he had been fouling our players all afternoon and probably should have been sent off earlier— John Bridges (@johnbridges754) 12 March 2018
Well his intellect matches his good looks— Martin Fretwell (@FretwellMartin) 12 March 2018
Didn't mention derby players kicking the crap out our boys or Nugents 2 handed shove on cash..— jamie parker (@parkers_jamie) 12 March 2018
Derby are a joke of a club end of
The pot calling the kettle black” springs to mind— John clifford (@Martinzoe01John) 12 March 2018
The irony that one of their players got booked for diving :)— Ian Russell (@IJRussell43) 12 March 2018
Even their own rag mentions Lawrence diving— ⭐wjm⭐ (@trickyred7980) 12 March 2018
Thats hilarious! They could have given Tom Daley a run for his money— Lynn Whiley (@lynnwhiley) 12 March 2018
The result extended Derby's winless run to seven matches - although they have only lost one of those - and saw them lose further ground on the automatic spots, which could explain Keogh's frustration.
Gary Rowett's side do, however, have a four point cushion over seventh-placed Bristol City and are 10 positions and 17 points better off than Forest.
