David Beckham said Tuesday that he was unlikely to return to action before November, meaning he could miss the MLS season.
The LA Galaxy midfielder ruptured his Achilles tendon playing for AC Milan in March, ruling him out of England's World Cup campaign, although he may still be involved in a non-playing capacity.
But it now appears he could miss the MLS season, which ends November 21.
"This is an injury that is going to take time to heal," Beckham told the MLS website.
"I'm only six weeks in after the surgery. I started therapy 10 days ago and just doing that every day. I kind of want to push it but with this kind of injury you can't. You just have to wait for it to heal and then move on.
"At the moment it's just getting the motion back into the ankle, the tendon, because obviously it's still repairing. I can't stretch too much, I have to wear a boot every day."
Arshavin dreaming of Barcelona
Arsenal forward Andrei Arshavin, a long-time Barcelona fan, still dreams of playing for the Spanish giants one day, the Russian international has said.
"Even playing just one season for Barcelona would make a pinnacle of my whole career," Arshavin, who missed Arsenal's 6-3 aggregate defeat by Barcelona earlier this month with a calf injury, said.
"Barca are the best team in the world and I enjoy their style of play so much. But after watching them against Arsenal (in the Champions League quarter-finals) the enjoyment has quickly turned into sorrow.
"They are so much better than anybody else at the moment," he said.
