Chris Kettings has had his loan period from Crystal Palace extended for a third time due to the continued absence of Bromley goalkeeper Alan Julian.
Kettings, 23, has impressed Hayes Lane chiefs since leaving Selhurst Park in September.
The current loan deal will expire on 22 December and cannot be extended further after this date.

Only a permanent transfer during the winter window, which starts on January 1, will allow Kettings to continue playing for the National League club.
Kettings signed a two-year deal with the Eagles in June 2014 after being released by Blackpool, but has failed to earn a first-team appearance for the Premier League club.
Ravens stopper Julian, 32, continues to receive treatment as he bids for a return.
