Paper submitted with repeated sentences in the introduction I have submitted a research paper to a peer-reviewed journal two months ago. It is my first submission. I have noticed two unfortunate elements in my introduction:


I wrote the same sentence twice in my introduction. 
In one of the sentences, I have repeated the same word twice consecutively. 


I think these mistakes came up with copying and pasting when I was trying to adjust my paragraphs in the introduction. Otherwise, I have already made grammar and spell check for the rest of the paper. Also, I am sure that the introduction is clearly written.

My question is that: can this kind of mistake (I think it is a minor mistake) cause a rejection by referees ? (The paper did not get a desk rejection, it is under review.) I will be really happy if you can share your experience regarding this kind of mistakes during the review process.
Regarding the repeated words, most people would not notice the the repetition at all. Regarding the sentence, they might be confused for a second, check back, see it's written twice, and continue as if nothing had happened.

Most will add a short note to the review, among those of other typos, that the sentence "..." appears twice. Nothing to be worried about, this alone will never cause a rejection of even major revision.
