CandH Exclusive by Hughie Southon
The central defender was subbed after just 12 minutes against Leicester City making way for Nayef Aguerd who went on produce a mediocre performance at the heart of defence.
It was unclear what had caused the problem as the former Chelsea man left the field not looking seriously injured.
But this morning a CandH key source inside the London Stadium explained that the player had not been comfortable before the game started and the precautionary move seemed sensible as a result when he was clearly feeling a problem.
The 28 year is known to have a problem in his knee which has seen him miss games in the past since his arrival at the club.
And Claret and Hugh was told this morning: “He felt something in his bad knee in the warm- up and never felt comfortable. Hopefully with the break he’ll be fine.”
