Cambridge United have handed a stadium ban to fans who booed players taking a knee before their home game against Colchester.
Other fans have been asked to undertake education around discrimination and equality before they are allowed back into the Abbey Stadium.
A handful of fans could be heard booing ahead of kick-off in the League Two fixture on December 15, even though it was quickly drowned out by applause.
The club was quick to condemn the actions of its supporters and vowed to launch an investigation, which has now concluded.
