Kenta Kurihara is currently schedule to play in two Ni-gun games beginning on the 4th (practice game against Industrial league JFE Nishi Nihon on the 4th and a Ni-gun game against Chunichi on the 6th). If Kurihara is feeling fine after those two games, he'll be added to the active roster on the 7th, right in the middle of a three game series against the Yomiuri Giants.
Kurihara told reporters that he would continue his training / rehab with the goal of returning on the 7th. He also said that he's still having good days and bad days with the bat.
If Kurihara returns to the active roster, he could spend some time at third base in order to allow Takahiro Iwamoto to stay a first.
