LONDON -- Chelsea goalkeeper Petr Cech had surgery for a skull fracture after being hit in the face by the knee of Reading midfielder Stephen Hunt.
Chelsea said Sunday it was too early to assess his condition.
"Chelsea Football Club can confirm that Petr Cech was transferred to the Radcliffe Infirmary in Oxford last night to the specialist neuro-surgical unit," the team said Sunday in a statement. "He underwent surgery for a depressed fracture of the skull."
Cech was hurt in the opening minute of Saturday's English Premier League match against Reading, which Chelsea won 1-0.
Chelsea manager Jose Mourinho called on the Football Association to take disciplinary action against Hunt.
"You see players avoiding the keeper by jumping or going with the foot for the ball, but when a player goes with the knee direct to the face, he doesn't want to avoid him," Mourinho said.
Cech's replacement, Carlo Cudicini, was hospitalized after being knocked unconscious in a collision with Reading defender Ibrahima Sonko while jumping to catch the ball in the 89th minute. He was released Saturday night.
