The Poland international, who hasn't played for BVB since their UEFA Champions League final defeat to FC Bayern München in May, underwent surgery on a troublesome hip injury in the summer.
BVB for life?
"I feel good," Piszczek told Borussen.Tv. "There are days when you don't feel particularly great, but that's normal at this stage of the recovery process. I'll definitely be fit for the second half of the season. I want to return before then but, if I don't, I won't be too downhearted."
The 28-year-old extended his contract with die Schwarz-Gelben until 2017 last month and says he might even end his playing days at Signal Iduna Park. "I'm happy here. I'm not the sort of player who likes to change clubs every two years. If everything goes well, I can imagine finishing my career at Dortmund."
Since joining the club from Hertha Berlin in 2010, Piszczek has made 94 appearances for Dortmund, scoring six goals.
