- Millwall fans booed the players for taking a knee in support of BLM on Saturday.
- Rooney states that the actions of supporters were 'disgraceful and mindless'.
Wayne Rooney, who is now a player-manager at Derby County, wrote on social media: "Yesterday I witnessed disgraceful and mindless behavior by a large section of the Millwall supporters in the stadium.
"Prior to the match we were aware of the possibility of a planned disruptive response during the taking of the knee in support of the BLM campaign, but nothing prepared us for what we heard.
"I was proud of my players and staff for not letting the fans deter them from continuing to present a positive and important message that taking the knee immediately before a game sends.
"We represent all sectors of out community regardless of colour, gender or sexuality. It is therefore really important to show respect and support of each other and do not tolerate or accept the actions of the mindless few."
Players in the Premier League and the Championship have been taking a knee before the kick-offs in support of the Black Lives Matter movement since the game's return to action in the summer.
