The 22-year-old was the victim of a heavy tackle from Daniel Didavi in the 2-0 win over Nurnberg, and wants to return in time for his side's trip to Hertha Berlin on February 18
The Germany international was the victim of a heavy challenge from Daniel Didavi during his side's 2-0 win over Nurnberg on Friday evening, and was replaced by Moritz Leitner after 23 minutes of the victory.
It has now emerged that the 22-year-old suffered an injury to the lateral ligament in his left ankle, which will keep him out for around a fortnight.
It is believed that the earliest that Jurgen Klopp could have Bender back at his disposal is for the away trip to Hertha Berlin on February 18.
However, the knock may require an extra week of recovery, meaning his comeback would be against Hannover on February 26.
The former 1860 Munich man will certainly be unavailable for the DFB Pokal match against Holstein Kiel and Saturday's clash with Bayer Leverkusen.
Bender also missed the final weeks before the Christmas break, after fracturing his jaw against Arsenal in the Champions League.
