In the Mishna 14b, and the psak of the Gemara on 15a, Rabbi Yosi is
mentioned as the author of the halacha in the Mishna. What did he say
and why does the Gemara not refer ot Rabbi Yochanan ben Nuri? Rabbi Yosi only seems to be telling the ma'aseh?
Since Rav Yosi determined that this ruling of Rav Yohanan was Halachah (as is obvious from the fact that he quotes the story in the Mishnah), it was brought in his name.
