Gem Archer has been hospitalised after sustaining a serious head injury last Thursday, August 1.
The 46-year-old musician is in a "stable condition" but will stay in hospital under observation until further notice following an accident last week.
A statement on the band's website reads: "Following an accident on the evening of Thursday August 1st, Beady Eye guitarist Gem Archer was hospitalised with severe head trauma.
''He is currently in a stable condition but continues to stay in hospital under observation. As previously reported, shows this week in Belgium and Japan have been cancelled.
''His family, friends and band mates thank everyone who have sent messages of support and well wishes so far and hope to see him back on his feet soon. An update on his condition will follow.''
The band, who play Dublin's Olympia Theatre on November 8th and 9th, pulled out of their gig yesterday at the Lokerse Festival in Belgium yesterday (August 7) and won't play at Summer Sonic in Tokyo, Japan, this Saturday (August 10) either.
The rocker's wife Lou wrote on Twitter over the weekend: ''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.''
