The data analyst, who was promoted to assistant director of football operations earlier this year, left the club at the start of the week, calling police to Motspur Park after his dismissal and has now been replaced by James Lovell ahead of the January transfer window.
Jokanovic and Kline are reported to have clashed on a number of occasions over transfers at the club, but Fulham's manager refused to comment on the American's departure and insisted he's fully focused on his work.
He said: "I am fully concentrated on my work and in front of myself and my players is a very important game and I don't have any comment from things that happen internally in my club.
"In general, in this moment I must be concentrated on my work and I have no intention of making a comment on this man, in general what I know is he is not here and he has left the club and that is it - I don't have any other information on this case.
"All the clubs use the data and we are going to try use this and all the tools that all the clubs in the world use, not only us, it's useful for us like it's useful for all the teams."
