Leeds United striker Patrick Bamford will be assessed this weekend after picking up a knee injury during Friday afternoons under-23s fixture at Elland Road.
Carlos Corberan named a strong line-up for the Professional Development League clash with Bristol City as Jamal Blackman, Jack Harrison and Lewis Baker were handed starting spots alongside the forward.
The 25-year-old arrived in West Yorkshire earlier this summer in a deal worth £7million from Middlesbrough but has found first-team minutes hard to come by.
Fellow forward Kemar Roofe has been in fine form in the opening month of the campaign etching his name onto the score sheet four times whilst grabbing two assists which saw him pick up the Championship Player of the Month award for August.
It was a double for Leeds as Marcelo Bielsa was handed the managerial gong following the Whites unbeaten start but the Argentine will now be sweating over the fitness of his marquee signing.
Bamford, who was handed an opportunity to gain some competitive minutes, opened the scoring in the 5-0 rout but left the field after the half hour mark following a clash of legs in the City box.
The striker appeared to indicate it was in fact the turf that caused the discomfort in the aftermath but United are yet to discover the full extent of his injury.
He will now be assessed over the weekend with Leeds waiting to find out how long he may be sidelined for although the Whites are hopeful it won't be a lengthy lay-off with the striker able to leave Elland Road and drive himself home following the incident.
17-year-old winger Jack Clarke produced a scintillating display in the victory as he notched two assists and a goal to stun the visitors to put Leeds in full control after just 25 minutes.
Clarke's first act was to provide Bamford a tap-in as the winger played a lovely one-two with Jordan Stevens which saw Clarke burst into the area and lay the ball on a plate for the striker at the back post.
Minutes later he again picked out a decisive pass from the right which found midfielder Callum Nicell alone on the edge of the box who lashed home a lovely strike to double the scoreline.
The youngster then grabbed one himself as Manchester City loanee Harrison turned provider with an inviting ball from the left which was met with a emphatic half-volley.
Stevens added a fourth after a fine one-two with substitute Ryan Edmondson before defender Robbie Gotts rounded off the afternoon with a curling effort from outside the box.
Corberan's men remain unbeaten after five league games and sit top of the northern section having picking up four wins and a draw so far this campaign.
