Callum Roberts suffered an injury as Newcastle United's Under-21s were beaten in their final match of a disappointing season.
Brighton and Hove Albion beat Peter Beardsley's side 4-1 at St James's Park tonight.
Newcastle's second string, without a victory since late January, had been looking to end their Under-21 Premier League campaign with a rare win.
But Division Two basement club Brighton had other ideas, and were 2-0 up by the 13th minute thanks to goals from Jack Harper, signed from Real Madrid last summer, and Joe Ward.
Luke Charman quickly pulled a goal back for United, but James Tilley and Jonah Ayunga netted in the second half to give the visitors a convincing victory.
Winger Roberts – who had been a threat down the right for United – hobbled off midway through the second half with what looked like an ankle injury.
Beardsley's team, 10th in the 12-team Division Two table, did not include any first-team players.
NEWCASTLE UNITED: Harker, Cobain, Gibson, Hunter (Laidler, 64) Williamson, Bailey, Roberts (Smith 65), Ward (Heaney, 64) Charman, Barlaser, Longstaff.
