Arsenal midfielder Jack Wilshere is back in training and could return in two weeks, says manager Arsene Wenger.
Wilshere, 23, suffered a hairline fracture to his right ankle in training on 1 August and it was thought he could miss up to two months.
But Wenger said the player's expected recovery time was three to four weeks.
He also confirmed Danny Welbeck, who has not played since April, is at least three weeks away from returning from a knee injury.
Tomas Rosicky has had knee surgery and will be out for over two months.
Midfielder Rosicky, 34, was injured while playing for Czech Republic against Iceland in a Euro 2016 qualifier in June.
Speaking before Arsenal's visit to Crystal Palace on Sunday, Wenger said: "Jack is back in training, I thought it would be six to eight weeks but it could be three or four weeks.
"He's in the second week now so he's on schedule."
Wenger added: "Tomas has had surgery on his knee. His agent said he will be out for one or two months, but it will be longer. How long exactly, we don't know yet."
