Conte: No need for Hazard to be selfish
He was, however, to return to the starting line-up for a FA Cup semi-final clash with Tottenham, with Antonio Conte eager to ensure that he did not go back-to-back fixtures without his first-choice shot-stopper.
Courtois was beaten on two occasions but still helped to secure a 4-2 victory to ease some of the discomfort he was feeling and offer welcome relief at the end of a testing spell that could have been much worse.
He told reporters: “I was afraid that the season was over. Fortunately, it was less bad.
"I have to say thank you to Chelsea's medical staff to get me fit. I do not think many people with a torn ligament already play after a week and a half.”
The Belgium international added on his showing against Spurs: "When I had to kick the ball against Spurs, there was a bit (of pain). Obviously I had to stand on my right foot which was not easy at times.
"But when you play with adrenaline, you feel good and you forget. I will get more treatment like I have for the last week - where I was with the physios from 10am in the morning till 5pm in the evening at Cobham.
"Tuesday won't be a problem. I'm getting better every day, so hopefully soon I will be able to play without a strap (on the ankle)."

Marcos Alonso will be another hoping to be involved in that tie, with the Spaniard having also returned to action on cup duty after sitting out a reversal at Old Trafford through illness.
He said on his struggles in Manchester which forced him to pull out of the game during the warm-up: "I was throwing up the night before and wasn't feeling very good. I tried to do the warm-up the following day but I was about to faint on the pitch.
“I did not want to ask for a substitution after five minutes, so I pulled out. I watched the first half in the directors' box but I had to go to the team coach to have a lie down on my own. I fell asleep (and missed the second half) as I was feeling so bad.
"I took a couple of days off and did not eat a lot. But I felt good against Spurs.
A lifetime of being ignored over for Kante
"I was a little bit tired in the first part of the game because it had been two weeks since I'd last played, but I'm ready for Tuesday."
