The Chunichi Dragons announced today that Takuya Asao was diagnosed with a rotator cuff tear in his right shoulder during an examination at a Nagoya hospital on Monday.
Asao suffered a similar injury in May last year and missed about four months. He currently does not feel pain and played catch at a distance of about fifty meters on Monday. He should be able to toss a bullpen session with a standing catcher some time next month.
The Dragons also learned more about the injuries sustained by 1st round draft pick Koji Fukutani and 4th round draft pick Shota Sugiyama: Fukutani has an adductor muscle injury in his right leg and Sugiyama a tibial collateral ligament injury in his left left elbow.
