Chelsea were dealt an early injury blow when Thiago Silva was forced off in the 19th minute during their 2-0 defeat against London rivals Tottenham Hotspur.
The 38-year-old went down clutching his knee after his crucial intervention thwarted Harry Kane inside the penalty area. Silva resumed for a brief period, before he was replaced by French defender Wesley Fofana.
The seriousness of his injury is not yet clear, but Chelsea will be made to sweat over his fitness prior to their next Premier League clash against Leeds United next weekend.
