Chelsea goalkeeper Petr Cech suffered a right calf injury in training and could miss the start of the Premier League season.
The Czech Republic international is fearful that this injury is a recurrence of the setback he endured last term, which kept him out of the line-up for a month.
Cech pulled up with the injury during a routine jog at training on Tuesday and could not continue at practice, according to The Guardian.
The 28-year-old’s right leg was placed in a protective boot and the team is waiting on the results of a scan to see the severity of the injury.
Cech suffered a torn muscle in his calf in the first leg of Chelsea’s Champions League last 16 match-up against Inter Milan, and the goalkeeper missed five matches, including the return leg against the Italian side, who went on to win the competition.
Chelsea are concerned that Cech will be ruled out of their match-up with Manchester United at Wembley in the Community Shield in two weeks, and when the club open their Premier League title defence against West Brom the following week.
