Arsenal midfielder Tomas Rosicky has undergone further surgery on a tendon injury.
The 28-year-old suffered the injury in an FA Cup tie against Newcastle on January 26 but has made slower progress than expected after originally having surgery back in May.
A statement released by Arsenal read: "Tomas Rosicky yesterday underwent routine revision surgery in Germany.
"The operation went as planned and Tomas will now spend at least a few weeks convalescing in Germany.
"Thereafter he will follow a tailored rehabilitation programme devised by our medical team."
