Rome  - Juventus veteran striker Alessandro Del Piero is to be sidelined for more than a month due to a muscler injury suffered while training Thursday, the Turin club's web site reported.

Del Piero, who turns 35 in November, has only played part of one Serie A game this season due a previous injury.

He pulled a muscle in his left thigh and promptly underwent a magnetic resonance after which he was diagnosed with a stop of up to 40 days.

Also injured in his left thigh while playing late Wednesday against Bayern Munich was the returning midfielder Tiago. The Portuguese's layoff is expected to last 20 days. dpa
