Chelsea have been rocked by the loss of goalkeeper Petr Cech for a month.

The Czech Republic international injured his calf in training yesterday and scans revealed a small tear.

Cech will miss the rest of the club's pre-season programme, and is unlikely to feature in the Community Shield against Manchester United at Wembley on 8 August.

A spokesman for Chelsea confirmed: "Petr will be out for around a month after scans showed a tear in his right calf.

"He is expected to miss the rest of the pre-season campaign."
