For Ozeki it takes three really good tournaments to make Ozeki but only two to lose the ranking. Many times when a rikishi gets injured it will take multiple bashos for them to fully recover because there is no break. The next basho is only 6 weeks after the end of one basho. If you don't train for several weeks, they get hammered the next tournament. I think Mitakeumi had this issue after being injured in January.
