IBF Orders Delgado, Biyarslanov to Renegotiate
After Lindolfo Delgado declined to travel to Saudi Arabia, the IBF has directed both fighters to renegotiate a bout for the vacant junior welterweight title.
Updated on Nov. 3, 2026 in Boxing
The IBF has ordered Lindolfo Delgado and Arthur Biyarslanov to renegotiate for the vacant IBF junior welterweight title after Delgado's team said he would not travel to Riyadh, Saudi Arabia, for a bout scheduled for October 31. The negotiation deadline is November 23, 2026.
Why it matters
The withdrawal stalls a championship bout that the two sides had already agreed to, leaving the vacant IBF title unresolved. The renegotiation order keeps the mandatory challenger process moving under the sanctioning body's rules.
The IBF ordered renegotiation after Delgado's team notified the sanctioning body on October 24, 2026 that he would not travel for the October 31 contest in Riyadh. The stub does not indicate whether the two fighters will reach a new agreement by the November 23 deadline.
The players
Lindolfo Delgado
Delgado is a professional boxer who was ranked the IBF's No. 1 mandatory challenger for the junior welterweight division.
Arthur Biyarslanov
Biyarslanov is a professional boxer who was the other fighter the IBF ordered to renegotiate for the vacant junior welterweight title.
International Boxing Federation (IBF)
The IBF is a professional boxing sanctioning body that ranks fighters and orders title negotiations under its mandatory challenger rules.
The details
Delgado secured the No. 1 mandatory challenger position on November 15, 2025, by defeating Gabriel Gollaz Valenzuela in an IBF-ordered eliminator. The IBF first directed Delgado and Biyarslanov to negotiate for the vacant title on May 27, 2026, and the two sides agreed to a bout before Delgado later declined to make the trip.
Timeline
November 15, 2025: Delgado wins the eliminator and secures the mandatory challenger position.
May 27, 2026: IBF orders Delgado and Biyarslanov to negotiate for the vacant title.
October 24, 2026: IBF is notified that Delgado will not travel to Saudi Arabia.
October 31, 2026: Scheduled bout date in Riyadh does not take place.
November 23, 2026: Deadline for the renegotiation.
Big Picture
The order follows the IBF's standard mandatory challenger process, in which an eliminator winner gains the right to a title shot that the sanctioning body can enforce through renegotiation orders. It shows how the IBF manages title sequencing when a ranked challenger withdraws from an agreed bout.
Fans following the junior welterweight division will not see the October 31 Riyadh fight, and the vacant IBF title stays unresolved until the two fighters reach a new agreement. Boxing followers tracking the mandatory challenger rankings should watch for a revised bout date or venue before the November 23 deadline.
The takeaway
Mandatory challenger orders can change quickly when a ranked fighter withdraws from an agreed bout, so title timelines should be treated as provisional until a new date is confirmed. Readers should check the IBF's rankings and announcements for the revised bout details.
What happens next
The IBF has set November 23, 2026 as the deadline for Delgado and Biyarslanov to renegotiate the bout.
