Bayern fans climbed over the barriers and trampled photographers on the sidelines.
Reuters photographer Kai Pfaffenbach wrote about the incident on social media:
"For those of you asking, I'm fine. A few bruises but no fractures or brain damage."
Bayern Munich has been in contact with the injured photographers, who have also received an apology from supporters.
The German giants will face Paris SG in the semi-finals of the Champions League.
