John Terry has suffered "no significant damage" following a scan on his right knee and will be out for weeks rather than months, Chelsea announced Monday.
Injury cut short Terry's return to action during the Blues' 1-1 draw at home to Liverpool in the Premier League on Sunday.
However, a Chelsea statement said Monday: "Today's MRI scans on John Terry's right knee thankfully show no significant damage to the cruciate ligaments.
"Chelsea Football Club's medical team will conduct further tests over the next two or three days once the swelling has subsided to determine how long John will be out, but it will be a matter of weeks not months."
Having to do without Terry for any length of time is still a blow to Chelsea, who have struggled defensively in their captain's domestic four-game absence while serving a racism ban and have slipped from first to third in the Premier League.
Terry is now in line to miss the European champions' potentially vital Champions League Group E game at Juventus, as well as league matches against West Brom and Manchester City.
He could even be a doubt for Chelsea's Club World Cup trip to Japan early next month.
