Brentford Football Club is pleased to announce Robbie Neilson and Nathan Byrne have extended their loan deals at Griffin Park until May 8.
Scottish defender Robbie signed initially on February 17 from Leicester City and has made 12 appearances.
Tottenham Hotspur youngster Nathan Byrne has made eight appearances since signing on February 21.
Both will remain with The Bees until the end of the regular season.
Brentford can also announce Nicholas Bignall and Trevor Carson have been re-called by Reading and Sunderland respectively.
Nicholas signed at the end of January and made seven appearances for The Bees.
He returned to Reading and scored twice for The Royals' reserve side against Exeter City yesterday afternoon.
Trevor returned to Sunderland last week after picking up a knock in training.
Sunderland's Scottish international goalkeeper Craig Gordon has recently undergone surgery on a knee injury so Trevor is to remain on Wearside as cover for The Black Cats.
He made one Brentford appearance, in a 3-1 victory against Sheffield Wednesday at Hillsborough.
