England boss Fabio Capello believes Theo Walcott did not suffer a serious ankle injury during Tuesday's 3-1 victory over Switzerland.
The Arsenal forward was stretchered off in the early stages of the Euro 2012 qualifying victory in Basel after his standing leg was clipped by defender Yves Oehri during the passage of play which led to Wayne Rooney opening the scoring.
Walcott was immediately taken to hospital after suffering what appeared to be a serious injury.
However, he returned to St Jakob Park afterwards where he told Capello the injury was only a "little problem".
"I spoke with Theo and he told me it is not a big problem," said the Italian.
"I said 'two weeks', he said less."
Arsenal boss Arsene Wenger will now be anxiously awaiting the return of the in-form winger.
Walcott has scored four goals in three domestic appearances for the Gunners at the start of the new season.
Wenger is currently without Nicklas Bendtner and Samir Nasri and learned on Tuesday that Netherlands striker Robin van Persie will be absent with an ankle problem of his own until at least mid-October.
