Chelsea goalkeeper Petr Cech has confirmed that he will undergo a scan on Monday to assess the groin injury that he picked up against Everton.
The 30-year-old was forced off at half time during his side's 2-1 win at Goodison Park in the Premier League on Sunday.
"I finished the half knowing I would not be able to continue after the break," Cech told his official website. "We will see how serious it is. We will know more after the medical check that I undergo tomorrow."
Cech was replaced by Ross Turnbull during the victory on Merseyside.
