Derby head coach Steve McClaren dedicated the club's biggest victory over Nottingham Forest for 116 years to Rams fans after they crushed their local rivals 5-0 at the iPro Stadium.
Midfielder Craig Bryson scored Derby's first hat-trick against Forest since Steve Bloomer in the 5-0 victory in 1898, with Jeff Hendrick and Johnny Russell completing a day of misery for the visitors. Derby had previously gone over six hours without scoring, but McClaren said: "We collect three points, but, for me, this is for the fans."
Forest assistant boss David Kelly said: "It was a disappointing catalogue of goals we gave away but credit where credit is due – they took their opportunities and were very clinical."
Leicester assistant manager Craig Shakespeare was satisfied despite the Championship leaders being held 1-1 by Blackburn, Jamie Vardy's goal cancelled out by Matt Kilgallon.
"As you get to the business end of the season, we have to see it as a point gained," he said.
The Foxes lead the division by five points from Burnley, who won 3-0 at Charlton, and have a 15-point cushion over third-placed Derby.
QPR scored twice in stoppage time to beat Middlesbrough 3-1 – the first gifted to Bobby Zamora when a freak bounce deceived home goalkeeper Dimi Konstantopoulos.
"It seemed both teams had accepted a draw. I really don't know where those two goals came from," Bond said.
"It was an amazing bobble, to be fair to the keeper, and it was a real gift for us."
Wigan and Reading complete the play-off places after 2-1 wins over Watford and Birmingham, respectively.
At the other end of the table, Blackpool recorded only their second win in 21 games through a single goal from Ricardo Fuller against Huddersfield Town.
Chris Brown's tap-in saw Doncaster complete a double over Sheffield Wednesday to ease their relegation fears, but Millwall slipped into the bottom three after defeat by Leeds, leaving boss Ian Holloway demanding a response against fellow strugglers Birmingham tomorrow. "I've never had such a vital game in my life," he said. "We need to drag Birmingham back with us."
Yeovil, second from bottom, were denied victory after Bolton came from 2-0 down to draw 2-2, while rock-bottom Barnsley were beaten 1-0 by a stoppage-time goal from Bournemouth's Steve Cook.
