The 22-year-old moved to Griffin Park for a second spell in February but made just three appearances before dropping out of the first-team picture.
Bees manager Mark Warburton told the club website: “We are naturally disappointed to see Liam recalled.
“He has been a model professional during his stay at Griffin Park.
“We fully understand though, as he has a part to play in Leicester’s fight for Premier League survival, and of course to prepare for a key role in England’s Under-21 European Championship campaign this summer.
“I wish Liam well for this season and in his future career.”
