LONDON (AP) -Exactly one year on from the on-field confrontation that re-awakened English football's struggle to eradicate racism, the fallout shows no sign of abating.
It started with a routine aerial challenge in a Premier League match last October. But when Chelsea captain John Terry racially abused Queens Park Rangers defender Anton Ferdinand not long after they had returned to the turf, an unforeseen chain of events were put in motion.
England's national team lost Terry as captain and later as a player, while Fabio Capello quit as coach. Ashley Cole and Rio Ferdinand, previously longtime international teammates now on opposite sides of the divide, were fined hundreds of thousands of pounds for Twitter outbursts about the case that resulted in a four-match ban for Terry.
But it is the damage to the reputation of English football that has been immeasurable - and it's not the sort of anniversary the Football Association wanted to share its 150th celebrations with on Tuesday.
Launching the FA's new golden-colored crest at Wembley Stadium, an exasperated FA chairman David Bernstein faced repeated questions linked to Terry's case amid a widespread belief that the player's punishment was too lenient.
Terry was cleared in a criminal trial in July but his ban from the FA is half that imposed on Luis Suarez, the Liverpool striker who racially abused Manchester United defender Patrice Evra in a Premier League match last October.
Such a disparity has led to some black players feeling let down by authorities, whose work to alter attitudes and perceptions during the past 20 years has now been eclipsed.
Bernstein seems to accept criticism that Terry's punishment should have been harsher.
"The FA received a certain, probably limited, degree of criticism for its processes in the Terry case - we will look at that," Bernstein said. "I think the tariffs will need looking at."
Such is the unhappiness about the effectiveness of anti-discrimination group Kick It Out that some players are considering forming a breakaway organization to combat racism.
"I don't think fragmentation is in anybody's interest," Bernstein said. "There are great passions involved here - I understand those - but I hope sense prevails and people work together."
Kick It Out has been particularly damaged by Manchester United defender Rio Ferdinand, brother of Anton, joining other black players in refusing to wear a T-shirt supporting the organization at the weekend.
The British government, though, is calling on black players to remain united within football, with Sports Minister Hugh Robertson cautioning: "This is a moment for cool heads, not hot ones."
"I can understand why feelings are running quite high on this, but actually I don't think this is the moment for football to fracture," Robertson said.
But pleas from ministers or football officials are unlikely to do little to quell the mounting fury.
This is a "watershed" moment, according to a lawyer working with players on the potential breakaway movement.
"The Society of Black Lawyers have been looking at the situation and held informal talks with a few black players," Peter Herbert told the BBC. "What we needed, essentially, was for black players themselves to take the initiative - which they now appear to have done - and form a progressive black footballers' association which can properly represent their interests."
The players who feel let down want tougher action against perpetrators of racism.
"Situations have happened and I don't feel the outcome has been just," said Everton forward Victor Anichebe, one of the black players who declined to wear a Kick It Out T-shirt before last weekend's matches.
Wales goalkeeper Jason Brown insisted it's not just about being "rebels."
"Football is a worldwide sport played by many a race and religion," he said. "We don't want to feel we can't play football because we're scared of getting abuse."
A solution is quickly needed.
"The current generation is feeling very frustrated and angry, they want improvements," said Gordon Taylor, chairman of the Professional Footballers' Association. "The frustration is boiling over now and, if we're not careful, we are in danger of self-imploding."
Taylor fears the worst if something drastic isn't done to unite the divisions within the English game.
"If we are not careful, this will set us back years," he said. "It would not only set back the game, it would set back the anti-racist initiative. It would encourage the extremists."
No matter how great a defender Terry has been for club and country, it seems certain his legacy will ultimately have stemmed from that one challenge 12 months ago.
