Benitez said that the injury is not serious and it should only be Saturday's clash that Terry misses.
"I am really pleased with the medical department, they are doing a great job," Benitez said. "We have just two players injured, Oriol Romeu, a long-term injury, and now John Terry has inflammation in his knee. It's not serious but he will not be available tomorrow.
"David Luiz, Petr Cech and even Demba Ba will be available. [They have] different situations but they will be available."
Chelsea are third in the Premier League, 16 points behind leaders Manchester United.
