The 28-year-old, who came on for the second half in Saturday's 1-3 defeat to Gladbach, is struggling with back problems.
Wolfsburg coach Mark van Bommel is now hoping that Brooks will be fit in time for the club's next game against Union Berlin on October 16.
'Die Wölfe' are winless in three Bundesliga games after winning their first four league matches of the season.
