Hoffenheim have dropped Arsenal loanee Reiss Nelson for their game against Nurnberg on Sunday.
The decision was said to have been taken for disciplinary reasons.
The 19-year-old has been with the Bundesliga team since the start of the season.
He managed six goals in his first seven games for the club, but he has struggled lately.
Nelson has only played four games in 2019 for Julian Nagelsmann.
Arsenal will be hoping that Nelson can salvage the situation and have a productive last few months of his loan spell, before returning to the club in the summer.
