Tomoya Satozaki and Yuki Karakawa likely won't be able to return to the active roster before the end of the regular season.
Lotte manager Norifumi Nishimura told reporters that Satozaki still experienced pain in his back when throwing the ball. Satozaki has played in three Ni-gun rehab games and has gone 4-for-8 with the bat. He told reporters on the 21st that his back was feeling better, but that he wasn't really receiving any treatment for it.
Karakawa is able to play some light catch, but still feels pain in his right elbow and has not been able to toss a bullpen session yet.
