The group was scheduled to perform at the Lokerse Festival in Belgium on 5 August (13) before hitting the stage at the Summer Sonic event in Tokyo, Japan next weekend (10Aug13), but both concerts have been axed.
A statement from the band's management reads: "Due to guitarist Gem Archer's injury, the band regret to inform fans that they will be cancelling their upcoming shows in Belgium and Japan until further notice. They are very sorry for any disappointment this will cause but as Gem is an integral part of the band there is no way that they can play without him."
It is unclear why the guitarist can't perform but the group's management officials insist an update on his condition is imminent.
Bandmate Andy Bell offered his support to Archer in a Twitter.com post on Saturday (03Aug13), writing, "Wanna wish my brother @gemarcherbe a speedy recovery."
And, on Sunday (04Aug13), Archer's wife Lou took to Twitter to thank fans for their well wishes. She wrote, "Thanks for all your support and well wishes during this awful time. I know he will appreciate it. Hopefully he'll be back on his feet soon."
Beady Eye's sets at the upcoming V Festival in England are still scheduled to go ahead as Wenn went to press.
The latest news is another black eye for Gallagher, who is reportedly suing The New York Post for libel over reports suggesting he impregnated reporter Liza Ghorbani, who is claiming child support fees from the rocker in a New York court.
Gallagher's lawyer Raoul Felder applied for a gagging order to silence Ghorbani at the end of last month (Jul13). She claims the rocker fathered her seven-month-old daughter Gemma.
Gallagher, who is married to singer Nicole Appleton, has vowed to fight the claims.
