The postponement of their latest tour comes just days after Biffy Clyro announced the biggest show of their career - headlining London's Finsbury Park in July 2026.
The trio have been one of the UK's biggest rock bands since their formation in the early 2000s, with eight top-five albums – four of them number one – amassing over a million sales.
Their international breakthrough came with 2009's Only Revolutions - which went platinum in the UK and received a Mercury Prize nomination.
The album contained two of their biggest hits: The soaring, anthemic Bubbles; and the windswept ballad Many Of Horror, which later became a number one hit for X Factor winner Matt Cardle (under the title "When We Collide").
Futique, released in September, is the band's first album in four years - following a hiatus where the band briefly considered calling it a day.
Its title is a portmaneau of the words "future and antique" - a word the band coined to describe songs and emotions that might seem ordinary in the moment, but that will eventually become valuable artefacts to be cherished and studied.
The record received rave reviews, with the NME calling it on of Biffy's "most personal and definitive records to date"; and Mojo magazine saying the trio had found a renewed sense of purpose.
"Band kiss-and-makeups can seem contrived, unconvincing; but this one feels genuine and sparky, [with] Biffy's urgent, passionate music oxygenated by time away."
