Kick It Out has been raising awareness for issues such as racism since the 1990s and began its latest annual two-week campaign on Thursday.
However, Reading striker Jason Roberts declared he wouldn't be taking an active part in the campaign and many others followed suit on Saturday, including Rio Ferdinand and the entire squads of Wigan and Swansea ahead of their Premier League match at Liberty Stadium.
It has been widely reported that the players are unhappy not just with Kick It Out but also the FA for a lack of action in combating racism in football.
Some believe the players' refusal to wear T-shirts during warm-up routines actually gives more publicity to the anti-racism campaign.
