Luke Molyneux earned a point for Sunderland on his return from a knee injury as they drew 1-1 with Hull City at Eppleton Colliery Welfare Ground.
The 19-year-old, who had been out with a knee injury since November, came off the bench to equalise in the 84th minute.
Hull went ahead after the break thanks to Keane Lewis-Potter's close-range finish.
Deon Moore almost doubled the lead with a bullet header that was well saved, before Molyneux netted with minutes remaining.
Sunderland finish Group H in third place, while Hull City are fourth, as both teams end their PL Cup campaign.
