Yes. I think it confuses people, because the anime did it out of order.

Manga = Mashiba vs. Kimura, chapters 270-289. --> Ippo vs. Sanada, chapters 290-314.

Anime = Champion's Road TV Movie - Ippo vs. Sanada --> OVA - Mashiba vs. Kimura.

They wanted Ippo to be featured in the movie, so they did it backwards.
