Sorensen sustained the injury in a 50/50 challenge with Kalou as he slid the ball home for Chelsea's second in a 7-0 Premier League romp at Stamford Bridge.
Some feel Kalou should have been penalised for his challenge, although he believes he touched the ball before catching the Danish shot-stopper.
Sorensen has been boosted by the news that he does not require surgery, meaning he should be fit for the World Cup in South Africa, and Kalou hopes he returns sooner rather than later.
"When I touched the ball, I touched his arm as well," explained Kalou.
"I hope he is not as bad as it looked. I hope he recovers well.
"After I scored, I watched the linesman and he didn't react negatively so I was really happy.
"I felt as though I touched the ball first and I was hoping it was allowed because the second goal was very important, as Stoke were pushing."
