The complaint forced Terry to miss the shock 3-0 home defeat against Sunderland on Sunday, which served to underline the importance of the defender to the Blues' title defence. The 29-year-old admitted that he was no longer able to play with the pain of the injury, which he has battled since the end of last season, and is worried he will now have to take a long-term break in order to fully recover.
"It is at a point where I cannot carry on with it," he told The Sun. "I used to be able to make it through games because the adrenalin gets you going and you blank the pain out. But now there is no decision to make. After games I'm in agony and not sleeping at all."
