Interim Chelsea boss Rafa Benitez has revealed that John Terry continues to struggle in his battle with niggling knocks.
The Blues skipper was expected to return to the fold for Thursday's Europa League clash with Sparta Prague , having travelled with the rest of the squad.
He was, however, unable to play any part in the continental clash after suffering yet another setback in his quest to return to full fitness.
Terry has been nursing a knee problem since November, with the center-half restricted to just 13 appearances in all competitions this season.
Benitez claims his captain is stuck in a 'vicious circle', but is pleased to see that Gary Cahill and Branislav Ivanovic have stepped up to the plate.
On Terry, the Spaniard said: "He had a little bit of a setback during the week.
"He is still not playing, but Cahill and Ivanovic are doing really well. We won the game the other day (against Wigan), we won today and they are doing really well, so we are pleased with them.
