Rakuten Eagles announced on the 9th that outfielder Daisuke Nakashima underwent "autologous osteochondral transplantation and lateral patellar retinaculum release in the left knee, and synovial resection of the right patellar ligament" at a hospital in Chiba Prefecture on the 8th. He will aim for a return to play while monitoring his recovery progress.

In his third year this season, he appeared in 125 games, recording a .274 batting average, 5 Home Runs, and 27 RBI. Although his playing opportunities decreased early in the season due to a slump in his batting form, his performance surged from July onwards. Overcoming that difficult period, he successfully returned to his position as a regular starter.

On the same day, it was also announced that outfielder Ryosuke Tatsumi underwent arthroscopic cleaning surgery on his right elbow at a hospital in Chiba Prefecture on the 8th.
