Nakamura said "I've had pain from my groin, an ankle and a calf since the end of last season.
"But the calf and ankle have been getting better in recent weeks.
"While I was playing for Japan, I took pain-relieving medicine. But it got worse."
As if that news was not bad enough it would appear that Nakamura's compatriot Koki Mizuno is also set to undergo surgery to alleviate problems with his knee.
He said: "I've been in pain since injuring my knee playing for the reserves against Gretna back in March. It's got so bad I can't play any longer."
Thank goodness we have strength in reserve! With players who can play wide such as Robson and Paul Caddis who impressed when he was deployed on the flank against Southampton plus the likes of Hartley and Brown who are all capable of playing in that position Celtic are well equipped to allow the Japanese genius to recover in time for the Champions League group stages.
Yours in Celtic
