Takuya Asao was examined at a hospital in Nagoya on Saturday and tests revealed that his condition is not severe. According to Daily Sports, he has a right shoulder strain that is on the mend. He suffered a similar injury during the 2009 season and managed to pitch through it.
The team trainer will accompany Asao to a second hospital on Monday for a second opinion. Results from both tests will be used to determine how he should proceed with his workouts.
At this point, the Dragons expect him to be ready for opening day.
