Brentford have extended the loan deals of Robbie Neilson and Nathan Byrne until the end of the season.
But on-loan keeper Trevor Carson has been recalled by Sunderland, while striker Nicholas Bignall has returned to Reading.
Scottish defender Neilson, 30, has played 12 games since signing from Leicester City on 17 February.
Spurs youngster Byrne, 18, has made eight appearances for the League One play-off hopefuls.
Carson, 23, whose one game for the Bees came in the 3-1 victory against Sheffield Wednesday at Hillsborough, returned to Sunderland last week after picking up a knee injury.
And he is to remain on Wearside as cover following Scottish international keeper Craig Gordon's kneer operation.
Bignall, 20, who arrived at Griffin Park at the end of January, made seven appearances but failed to score.
