Last season, Fulham managed to get the furthest out of all the west London clubs, beating Premier League Hull City before eventually losing 3-0 to Tottenham in the fifth round.
Brentford made it to the fourth round of the famous competition where they faced a west London derby with Chelsea, but were beaten 4-0 at Stamford Bridge by the eventual Premier League winners.
It was a short FA Cup run for QPR, who went out of the cup in the third round when they were beaten 2-1 by Blackburn Rovers at Loftus Road.
The draw for the third round takes place on Monday December 4 at around 7pm, and we'll be running a live blog with all the ties right here on GetWestLondon, and here are the all important ball numbers you need to know for the west London teams:
Brentford - 7
Fulham - 17
QPR - 32
