Charlton Athletic paid tribute to PC Keith Palmer, who died in the Westminster terror attack last month, at their game against Milton Keynes Dons on Tuesday.
PC Palmer was a season ticket holder at the League One club, and his brother John Curtis led the teams onto the pitch at The Valley, followed by 22 of his police colleagues.
Representatives from both clubs and the police laid wreaths in the centre of the pitch before a minute's silence was held.
PC Palmer's seat remained empty, having been changed from red to white for the rest of the season and bearing his warrant number 'P204752'.

The seat had previously had a red and white club scarf draped over it following the news of his death.
Charlton's players donated their appearance fees for the match to PC Palmer's family, while the club gave 50 percent of the ticket sales.
Both teams wore black armbands, while Charlton's players wore special shirts which included his warrant number on the sleeves.
Outside the ground, flowers from supporters and other clubs were laid around a statue of former Charlton goalkeeper Sam Bartram, where in due course a permanent memorial stone to PC Palmer will be placed.
Charlton lost the match 2-0, but manager Karl Robinson said: "I felt we showed what a great club this is.
"It's been difficult, speaking to family members and to the police who served with him, and they are still hurting. It's hard to put into perspective.
"The fans, the players, the MK Dons players and staff, everyone handled themselves impeccably."
Milton Keynes boss Robbie Neilson said: "Someone's lost their life, a family has lost a father and a husband, so it puts football in perspective."
