Former Arsenal manager Arsene Wenger has decided not to stand against Gianni Infantino as a candidate in Fifa's presidential election.
The Frenchman had been considering running for the job but sources have told BBC Sport that he has ruled himself out.
Current world football chief Infantino's position was plunged into crisis by a backlash caused by his failed plan to sell commercial stakes in the World Cup to private investors.
Wenger - who is Fifa's head of global development - would have had the backing of European football's governing body Uefa, which has spearheaded opposition to Infantino.
On Saturday, French newspaper L'Equipe reported that Wenger was unlikely, external to challenge his boss.
Wenger has credibility throughout the footballing world, and this will be a significant boost to Infantino as he seeks a fourth term as president.
Uefa is said to still be hopeful of finding an alternative candidate before Wednesday's deadline.
One influential figure in the group of stakeholders opposed to Infantino told BBC Sport the news was "a real shame".
"Even if not perfect, I do think he could have galvanized many around the world," they added.
Former Tottenham defender Ramon Vega was the first person to put his name forward in October.
Japan Football Association honorary president Kozo Tashima has also announced his intention to stand.
However, sources have told BBC Sport that the 68-year-old has not yet secured the necessary five endorsements from member associations ahead of Wednesday's deadline but is "still fighting hard".
Amid the fallout over FFE, Wenger, who has traditionally been loyal to Infantino, distanced himself from the aborted plot.
"I was not involved in this strategic plan and first became aware of the project through media reports," Wenger said at the time.
“The decision to withdraw the project was absolutely necessary and beyond question, because I firmly believe in an independent Fifa that serves our game with commitment, transparency and integrity.”
Infantino has retained support in South America, Africa and Asia, and recently insisted he has the backing of the "vast, vast majority" of world football.
