Ze Roberto set for month-long layoff

BERLIN - Hamburg midfielder Ze Roberto will be out for at least four weeks after having surgery for an ankle injury on Tuesday, the Bundesliga club said.

The Brazilian, who joined in the close season from Bayern Munich, has been instrumental in keeping Hamburg just four points off the top despite missing several key players through injury including strikers Mladen Petric and Paolo Guerrero.

"He will be out for at least four weeks which means that he will return to the team after the winter break," the club said.
