Scott Harrison is seeking a new opponent for the next defence of his WBO featherweight title after the withdrawal of Juan Manuel Marquez.
Harrison has not fought since last November
Harrison had been ordered by the WBO to face interim champion Marquez by 9 November or be stripped of his title.
But the Mexican has opted to take another fight on 21 October instead.
It is another blow to Harrison, who pulled out of his last scheduled contest in May at short notice because of depression and alcohol problems.
He should have fought Dominican Joan Guzman earlier this year, too, but his opponent also withdrew.
Harrison, 29, has not fought since November last year.
He was also charged with six criminal offences earlier this month, including three assaults and one fraud.
However, Marquez's withdrawal could be a blessing in disguise for the Cambuslang fighter.
The Mexican, a former WBA and IBF title-holder, has mixed in more exalted company and would have been a tough proposition.
In light of Marquez's decision, it is unclear whether Harrison must still meet the WBO's 9 November deadline.
