The BBC has the latest on Walcott:
Arsenal forward Theo Walcott will miss the start of the season with a knee injury, but is set to resume training by the end of August.
The England international, 25, ruptured the anterior cruciate ligament in his left knee during an FA Cup third-round tie against Tottenham in January.
Walcott missed the rest of the 2013-14 season and the World Cup in Brazil.
"We expect him to be back in full training at the end of August," said Arsenal manager Arsene Wenger.
"Theo has a good basis, which is what he's working on now," added Wenger, who also predicted that Walcott's return to contention would be "very quick" once he was back in full training.
