Fulham have recalled winger Alexander Kacaniklic from his loan spell at Burnley.
The 21-year-old has made six appearances for the Championship side since joining them at the start of March.
But he has now been recalled by Martin Jol and could be involved in this weekend's home clash with Arsenal.
The Sweden international has already appeared for Fulham 19 times this season, netting three goals.
And one of those under scrutiny, Dominic Dell, scored the only goal of the game with a classy finish from the edge of the area after 70 minutes.
It was the forward's first run out for Vale's second string since being released by Wolves.
The other trialists were Irish midfielder Gary O'Neill, who has also come from Wolves, and big central defender Ejiro Okosieme, who is surplus to requirements at Middlesbrough.
Defender Joe Davis and winger Ryan Lloyd, both of whom came through the academy at the Burslem club, were the only two players to feature against Burton with any first-team experience.
