Borrowdale makes return to QPR
The 23-year-old left-back picked up the problem during the Seagulls' 3-1 defeat by Southend at the Withdean Stadium on Tuesday night and is expected to be sidelined for a fortnight.
Borrowdale joined Rangers from Coventry in November, initially on loan, but did not figure in a single first-team game and moved to Brighton last week.
The Southend match was Borrowdale's second appearance for the League One strugglers.
