Joe Gelhardt was handed his first start for Sunderland, who salvaged a 1-1 draw against Millwall at The Den courtesy of Dennis Cirkin's 81st minute equaliser.
Jake Cooper opened the scoring for the Lions in the 59th minute, but Sunderland kept their Championship play-off hopes alive by registering a point in the capital.
Gelhardt joined Sunderland on loan from Leeds towards the end of the January transfer window, and is now tasked with replacing star striker Ross Stewart, who has been ruled out with an Achilles injury for the rest of the season.
