Your first post asking this question was right.

The verbs are
suffered
is causing

Yes, you are correct. "Suffered" and "is causing" are both verbs in the given sentence.

The verb "suffered" is in the past tense, indicating that the injury happened in the past. It describes the action of experiencing or enduring something, in this case, an injury to the knee.

The verb "is causing" is in the present continuous tense. It describes an ongoing action that is happening in the present. In this context, it explains that the injury to the knee is currently resulting in pain and discomfort.

By identifying the verbs in a sentence, you can better understand the actions or states being described.
