Yuji Kaneko did not play in tonight’s game against the Softbank Hawks at Seibu Prince Dome because he hurt his right groin while running the bases on September 23. He will be examined by a doctor on September 26. The Seibu Lions will wait a few days before they decide on his status.

[UPDATE 9/27 @ 6:35pm]
Kaneko was taken off the active roster today with pain in the back of his right knee.
[UPDATE 9/28 @ 1:29pm]
Many of the reports yesterday did not mention any issues with his right groin, but Sponichi does include right groin in their report this morning. The Lions gave Kaneko a couple of days, but decided to take him off the active roster because he was still having problems walking.
