Development Squad midfield player Tyrell Miller-Rodney has returned from his loan at Skrill South side Maidenhead United until.
Tyrell joined the Berkshire side on a Youth Loan last month.
He played seven games for Maidenhead but missed their loss to Bromley on Saturday with an injury.
That injury is likely to rule him out longer term so the deal, which expired on Sunday, March 23, has not been renewed.
Ose Aibangee, Brentford FC Academy Director, said: “This has been a good loan move for Tyrell and he has done well for Maidenhead.
“It is his first real loan move and he has dealt with the pressures of playing for a team fighting relegation.
“He has been playing in a team with games Saturday, Tuesday, Saturday and coping with the physical demands of that.
“Like the other players we have sent to Maidenhead recently, he has been well looked after.
“We hoped he could go back to Maidenhead and help them in their fight against relegation but his injury means that will, unfortunately, not be possible.”
Tyrell, 19, joined Brentford on a scholarship in 2011, came through the Youth Team ranks and signed a one-year professional deal in the summer of 2013.
Tyrell played 11 Development Squad games in 2012/13 and has gone on to make nine appearances in the Under-21 Professional Development League Two South this season, scoring twice.
The combative midfielder was an unused substitute in Brentford’s Capital One Cup defeat away at Derby County in August; his first taste of First-Team action.
