Yokozuna Musashimaru, the second foreign wrestler to reach sumo's ultimate rank, decided to retire Saturday after his comeback bid at the Kyushu Grand Sumo Tournament ended in disaster.

The Samoan-born yokozuna, whose real name is Fiamalu Penitani, has been plagued with a nagging wrist injury and had missed the better part of six straight tournaments leading to the Kyushu meet.

Nowhere near his top form and faced with the grim reality of possible retirement, Musashimaru, a 12-time Emperor's Cup winner, decided to put his career on the line but was forced to call it quits after losing to Tosanoumi on Saturday.
