Anderson has joined full-scale training at Manchester United.
The Brazil midfielder has recovered from a knee injury suffered midway through last season.
United boss Sir Alex Ferguson revealed: "Anderson started football training yesterday, which is good news.
"Rio Ferdinand will still not be back until the end of September. His injury before the World Cup was a complete accident, just one of those freak things. It was a training accident and you have to treat it in the proper way."
