Brentford aren't in action over the weekend due to the international break but two contracted players are set to be in action for the loan sides.
Jack Bonham and Tom Field are out on loan at Carlisle and Bradford City and they will be looking to gain further match experience with the Bees having the option to recall the pair in January.
Konstantin Kerschbaumer's Arminia Bielefeld side are not in action, also due to the international break.
GetWestLondon takes a look at the two fixtures which can involve Bees players over the course of the season.
Jack Bonham (Carlisle vs Yeovil)
The goalkeeper has had a reasonable time of things with the Cumbrians, who sit 16th in League Two.
He has made 12 league appearances plus three in cup competitions and has kept three clean sheets in the league.
They face a Yeovil side who sit one point and one place below them in 17th with Carlisle hoping to cut the seven point deficit to the play-offs, while extending the six point gap to the bottom two.
Tom Field (Bradford City vs Plymouth)
The left back has played a bit-part role at Valley Parade so far this season, limited to just six games in the league.
The 20-year-old will hope to force his way back into a Bantams side that are six points adrift of top two Shrewsbury and Wigan Athletic.
They face a Plymouth side who sit bottom of League One on 11 points, four adrift of 20th placed AFC Wimbledon.
Konstantin Kerschbaumer (No game)
The Austrian midfielder's loan side are not in action at the weekend and currently sit in ninth place in 2. Bundesliga.
They are 12 points behind leaders Fortuna Dusseldorf, while they are two points adrift of a play-off spot.
The German side are six clear of the relegation play-off spot, while a further two ahead of Philipp Hofmann's Greuther Furth side who occupy the final play-off spot. Hofmann's former side FC Kaiserlautern are currently bottom of the league.
