The Denmark international was initially believed to be set to miss out with a slight knock, but his representative Per Steffensen has since confirmed the centre-back had been declared fully fit for the tie.
With Manchester City and Barcelona both believed to be keen on the 27-year-old, the continuing uncertainty over Agger’s future will be of concern to manager Brendan Rodgers as he looks to rebuild his inherited squad at Anfield.
"He is not injured in any way," Per Steffensen told Politiken.
"Only the club and the manager can answer to why he is not in the squad."
However, Steffensen was quick dismiss suggestions that Agger had handed in a transfer request on Merseyside, although revealed that the club had yet to offer the player an extension to his current deal, which expires in 2014.
"But the reports of Agger handing in a transfer request are purely nonsense. He is very happy at Liverpool,” he added.
"We have not heard from Liverpool with regards to a contract extension."
