Arsenal take on Oxford United in the final fixture of the FA Cup third round on Monday night.
The Premier League leaders head to the Kassam Stadium with the victors having the pleasure of facing Manchester City in round four.
The Gunners will be wearing a different kit to their usual red and white home shirts this evening, despite no obvious kit clash with The U's yellow tops.
They also won't be wearing either of their away strips.
The north Londoners will be donning an all-white kit tonight, and for a very good reason. They do so in support of the No More Red knife campaign and it will be the second year they have got behind the initiative.
Removing the red from the Gunners' short is seen as a symbolic act, with the colour seen as the blood. Arsenal's Women team will wear the strip when they play Chelsea later this month.
"It's great. I think the support the club have given to the community and vice-versa, and the fact that we are constantly doing these kind of things is very important," said Gunners boss Mikel Arteta ahead of the game. "It helps keep a lot of people - especially young people - safe in our community."
