Thiago Silva suffered knee ligament damage against Tottenham which could see the Chelsea defender sidelined until after the international break in another major setback for manager Graham Potter.
Scans on Monday revealed the extent of the injury that forced the 38-year-old centre back off during Sunday’s 2-0 defeat.
Chelsea did not confirm how long Silva would need to recover, as that will be determined by his rehab process and how he responds to treatment. However, initial expectations are that he could be out for up to six weeks.
Chelsea will be without a key defender in a pivotal week for Potter.
