John Terry will be asked by UEFA to wear an anti-racism armband if he captains Chelsea against Shakhtar Donetsk on Tuesday.
All club captains will be asked to wear a 'United Against Racism' armband as part of a week of action by European anti-discrimination body FARE.
Terry last week accepted a four-match ban for racially abusing QPR's Anton Ferdinand, but the suspension only applies to domestic matches meaning he is eligible to play for Chelsea in the Champions League, and he would be expected to skipper the side.
UEFA said in a statement: "Every team will be accompanied onto the pitch by children wearing 'Unite Against Racism' T-shirts and the captains will be asked to wear a 'Unite Against Racism' branded armband."
The campaign will be promoted at 40 matches across the Champions League and Europa League this week, with films broadcast on giant screens and special announcements made on stadium loudspeakers to encourage fans to join UEFA in its call to unite against racism in football.
