Clinton Woods' successful defence of his IBF light heavyweight title against Glen Johnson in Bolton on Saturday has caused problems for Joe Calzaghe.
Saturday's fight was the third IBF title defence for Woods
Johnson had agreed to fight Calzaghe, the WBO and IBF super middleweight champion, if he beat Woods.
But the split-decision win for Woods has thrown those plans into disarray.
No love is lost between the champion from Sheffield and Welshman Calzaghe, or their respective camps, and a meeting might be tricky to engineer.
While a clash between the two Britons might be box office gold in the UK, it would raise little interest on the other side of the Atlantic where Calzaghe has been chasing the big-money contests.
Before the fight in Bolton Calzaghe said he wanted a Johnson victory in order to set up a lucrative fight with the US-based Jamaican next year.
That added further fuel to Calzaghe's already volatile relationship with Woods.
"It is doing my head in that all people are talking about is Calzaghe," said Woods before his defence.
"They are conjuring up these little plans, and when I reverse them I will have the biggest smile on my face."
Woods will no doubt have awoken on Sunday morning grinning from ear to ear, having achieved exactly what he set out to do.
The Sheffield man, who needs rehabilitation on the damaged elbow he suffered on Saturday night, hinted he may even opt for a rematch with Johnson to face him for a fourth time - leaving Calzaghe sidelined.
Calzaghe will return to the ring against Cameroon's Sakio Bika in Manchester next month and his promoter Frank Warren has been working on a major fight early next year for the Welshman.
Top of the list of ideal candidates was Johnson, who won and drew in his two previous meetings with Woods before relinquishing the IBF belt for a non-title super-fight against Antonio Tarver.
But now Warren may now have to deal with Woods and his promoter, Dennis Hobson.
The two promoters are bitter rivals and their relationship was further strained when Warren outbid Hobson to actually stage Woods' clash with Johnson.
However, in July Hobson had publicly offered the Calzaghe camp £1.5m if he would move up to light heavyweight and fight Woods.
"It would be a dereliction of duty for the fight to go begging because of promotional rivalries," Hobson said at the time.
A fight between the two home-grown 34-year-olds would be welcomed by the British boxing public, but the path to that clash will take some tricky navigation.
