expects to be in a position to make a definitive announcement on Ben Chilwell’s injury over the weekend.
The England left-back suffered the injury in stoppage-time as Chelsea came from behind to beat Dinamo Zagreb 2-1 in their final group game on Wednesday.
Chilwell, who was later pictured leaving the ground on crutches, did not start the Blues’ 4-1 thrashing at Brighton last weekend with the club attempting to manage his workload after battling back from an anterior cruciate ligament injury.
Potter acknowledged this latest setback could harm the 25-year-old’s hopes of being part of Gareth Southgate’s squad, with England playing their first game of the tournament in Qatar against Iran on November 21 but claims it is too soon to rule the player out altogether.
Speaking ahead of Sunday’s London derby against Arsenal, Potter said: ‘He’s going for a scan later this afternoon so we’ll find out how he is then and there will be an update tomorrow.
‘He feels OK but aware of the injury. We need to let the swelling settle down, hence the delay of the scan. We’ll know after that.
‘He’s OK and at the moment we’re hopeful until we get the diagnosis. From there we will aim to him back fit or strong.’
Potter also confirmed that Mateo Kovacic was in contention to feature against Arsenal on Sunday having missed the midweek Champions League victory, but goalkeeper Kepa is unlikely to play again before the World Cup after suffering a foot injury.
Chelsea head into the game lagging behind their local rivals and Potter has warned his team they will be made suffer unless they match the league leaders for intensity.
‘If we don’t do that in any game [matching the intensity] it’s going to be a challenge for us,’ he said.
‘We have to be ready for a special game and we have to be ready to play the football to get us a result.’
On Blues recent record against the Gunners, he added: ‘Recently, it hasn’t gone so well if I’m not mistaken, so we have to do better there.
‘It’s a London derby and anything can happen in the game. We want to be positive, play well and get the crowd involved in the game.’
