The Czech international is set for another stint on the sidelines after sustaining a thigh injury minutes into his first appearance of the season.
Arsenal midfielder Tomas Rosicky has been left "devastated" after his latest injury setback, according to Arsene Wenger.
Rosicky picked up a thigh injury just three minutes after coming on in his side's 2-1 win over Burnley in the fourth round of the FA Cup on Saturday, in what was his first appearance for the club this season.
The 35-year-old Czech Republic international had been out of action since May 2015 due to knee surgery but Wenger is hoping he will not be sidelined for long this time around.
