The German club has excluded the Dane, who has netted twice in the Bundesliga this season, from training duties and are expected to determine his future in the coming days.
Nicklas Bendtner looks set to leave Wolfsburg after being told by the club he no longer needs to attend first-team training.
The former Arsenal striker has struggled to settle since joining in 2014 and has faced a number of disciplinary problems this season, including fines for being late to training.
Bendtner also landed himself in hot water after posting a photo on social media of his Mercedes, which angered the hierarchy of the club as the team is sponsored by Volkswagen.
