Boyata was a £9m target for Fulham this summer, but Celtic refused to let the Belgian defender leave. The 27-year-old's agent said this week that his client wouldn't play unless he was 100 per cent fit due to him being in the last year of his contract.
Speaking after the 3-2 aggregate loss, Rodgers said: "Yes, we were obviously missing our two best centre halves this evening unfortunately.
"My concentration really until I get back is only with the players that are here.
"But yes, Dedryck would have been fit to play."
