A post on the band's official Twitter feed appeared to reveal the sleeve and release date for 'Under The Westway'.
"#blur #underthewestway @blurofficial / 7.15pm (BST) / 2nd July," the message read, with a link to the image above.
Yesterday (June 19), the account posted a different image with the same date, leading to speculation that the release could be a double A-side with another track called 'The Puritan'.
'Under The Westway' was performed by frontman Damon Albarn and Graham Coxon ahead of this year's Brit Awards during a live show at the O2 Shepherd's Bush Empire in London.
The band play London's Hyde Park on August 12 with support from New Order, The Specials and Bombay Bicycle Club.
Albarn has suggested that the gig could be the band's last, though he later said that the band was not finished.
