The defender didn’t figure in the Reds’ opening summer fixture at Tranmere Rovers on Thursday having only returned to Melwood on Tuesday.
Lovren will, however, play a part in the contest at Valley Parade.
Jürgen Klopp told Liverpoolfc.com: “Dejan will be back. With him, we had the same thing we will do now with the guys who came back today. But he will be playing tomorrow, of course.”
Liverpool used 23 players during the 6-0 win at Tranmere, with 11 changes made at half-time.
Klopp confirms the Reds will do something similar against Bradford.
