Millwall fans were allowed to return to the Den for the first time since the coronavirus outbreak and they reacted by booing both sets of players as they took the knee as a mark of support for the Black Livers Matter movement.
Following the death of American George Floyd earlier this year, all players in the Premier League and Football League show their respect to his campaign before kick-off.
However, Millwall supporters were not in favour of their club following suit.
Around 2,000 home fans were permitted into the south London stadium for the first time this season and boos rung out as all 22 stars put one knee on the grass.
Millwall released a statement last night in anticipation of fans returning to the Den.
Lions boss Gary Rowett joined his players in explaining why the club will continue to take the knee.
Manchester United and England legend Wayne Rooney is in caretaker charge of Derby and he was expecting to get stick off those in attendance at the Den.
“I am looking forward to it, it’s great when the fans are in,” said Rooney.
“There is banter going on, unfortunately there will be no away fans there. I am sure the players and myself will hear everything that is said!
“I was looking forward to playing at Millwall (last season) with the fans there, but we had to play without fans.
“It will be nice to have a few fans in, the fans are a big part of the game.”
Derby sacked ex-manager Phillip Cocu last month and his long-term replacement is still being hunted.
