We are working on his ligaments, so we are expecting a return to full fitness in two to three weeks.Pep Clotet.
The on-loan Chelsea centre-half dislocated his shoulder in Saturday's away win at Reading and subsequently had to attend the local hospital to have it put back in place.
Understandably there were concerns that the 22-year-old may need surgery.
But following talks between the respective medical professionals at Blues and his parent club Chelsea, it appears that an intensive course of treatment could see him back in the frame in as little as two to three weeks.
"Jake obviously had his shoulder dislocated at an early stage of the game in Reading," said Blues' Head Coach Clotet
"He was taken to hospital, the shoulder was put back in place, our medical team spoke to Chelsea's medical team and they all agreed they are going with a conservative treatment on him - so no surgery because there is no damage on the bones
"We are working on his ligaments, so we are expecting a return to full fitness in two to three weeks. Three weeks would be an achievement.
"I have spoken to Jake as well, he is focused, already working on it. The important thing is there was no big damage, it just popped out, popped in after in the hospital, so good news."
When Clark-Salter left the field at the Madejski Stadium he was replaced by Wes Harding on the left side of the middle of defence.
Heading into Wednesday's home game against QPR, it is going to be a choice between Harding and Geraldo Bajrami for the role, with Marc Roberts still unavailable because of an ankle injury.
"It is a chance for one of them to step in," added Clotet.
"I always said in this squad everyone is ready, everyone is eager to help.
"They have the right to want to play more and every player finds his chance, then it's about taking it.
"Wes is a player who has proved we can rely on him, he has proved himself in this Championship, he proved himself in this position on Saturday.
"It was not an easy task and he is quick as well, strong, very focused. I have no doubts about it.
"He was there as a cover for the whole defence, I knew he could cover for every position - possibly one of the most difficult positions is that left centre-back - he did very well.
"And we have Geraldo with us. He knows how we play, the Under-23s follow the same love for the game.
"Geraldo has been training with us a lot and actually for the last month and a half has been with us every day, so he is ready as well."
