The experienced 30-year-old has made a total of 22 starts for the side so far since arriving from the Sky Blues on his initial loan at the end of August.
19 of those starts have come in the league, taking his career total to 247, just three off a quarter-of-a-century milestone.
Brown returns to the side after his initial loan spell expired following Saturday's 2-2 draw at Bradford City and has re-registered with the club in time to face Portsmouth in the quarter-final of the Leasing.com Trophy.
