The problem with wrists is that they usually never heal fully unless a really significant amount of time is taken off to allow it to heal. Just too many bones and tendons in there, and if something ends up misaligned, then he's screwed. I think he should be able to come back by Aki and do fairly well for a while, but not quite back up to his old form. Besides the injury, he's starting to get a little long in the tooth for a power rikishi, and it seems like he's at about the age where they generally start to fall off. Thus, I'm not sure if I see many more Yusho ahead of him, but he's got enough gas left in the tank to go for about another year or two if he doesn't get injured again. However, if he reinjures his wrist, he'll be done. However, even if he misses the next two Basho, I doubt there will be inordinate pressure for him to retire...everyone here knows about the state of the sports popularity, and with most of the other guys who could help revive interest somewhere on the two-year horizon to make it to Sanyaku (i.e. down in lower Juryo at the moment, and a couple of guys in mid-Sandanme), I doubt the Kyokai will force one of their big drawing cards out if he feels he can be ready to compete before next year.
