Borussia Dortmund advanced to the third round of the German Cup on Wednesday with a 2-0 win at second-division club Hannover.
Dortmund were looking for a confidence-building performance after just two wins from their previous eight games across all competitions -- the nature of the team's 2-0 loss at Union Berlin on Sunday was still smarting -- but it was far from convincing in Hannover.
The home team created more chances and should have equalized before Phil Neumann conceded the penalty for a foul on Bellingham, who had come on as a substitute.
It was the first game in any competition that Bellingham hadn't started for Dortmund since December, as coach Edin Terzic attempted to give the England midfielder a break.
American Gio Reyna also came on for his third appearance since returning from injury.
Dortmund forward Karim Adeyemi was sent off late for a tactical foul to deny a clear goal chance.
