Arsenal boss Arsene Wenger provided injury updates on Theo Walcott and Calum Chambers following the 1-0 win over Doncaster in the third round of Carabao Cup.
Both players were forced to leave the pitch on Wednesday night with their respective injury concerns.
About Walcott, Wenger said: "He had a kick behind his knee at half-time and in the second half he got another kick.
"I don't think it's big, it looks to me a kick - not more than that."
He added: "Chambers is injured again on the hip, yes."
