London: Arsenal winger Theo Walcott has flown home from the club`s training camp in Germany after the recurrence of a niggling ankle injury, the club confirmed Wednesday.
Walcott, 22, returned to London for further "investigation" of the injury manager Arsene Wenger said as the Gunners prepare for their season-opening Premier League game against Newcastle next month.
"Theo went home early and was due to have an MRI," Wenger said on Arsenal`s official website.
"It is an ankle injury that comes and goes. We need some more investigation because sometimes he`s completely free of it and sometimes it affects him. But we had to send him back because he couldn`t practice anymore."
Wenger also revealed youngster Conor Henderson -- stretchered off in Saturday`s 2-1 win over Cologne -- faced up to six months out after suffering a serious knee injury.
"Conor has a knee injury and it looks as if it is a cruciate. That means unfortunately that he will be out for six months at the very least," Wenger said.
