Robbie Henshaw will miss Ireland's opening game of the World Cup against Scotland on Sunday.
The Leinster centre developed a hamstring injury during Ireland training.
Defence coach Andy Farrell said on Wednesday that Henshaw is making good progress but will be unavailable for this weekend. However, there is hope that he will be able to face Japan on September 28th.
There is better news regarding Rob Kearney and Keith Earls. Both the fullback and the winger are available for selection against Scotland after recovering from calf and thigh problems respectively.
"Rob and Keith Earls ran well, and trained well," Farrell is quoted as saying by RTÉ.
"There's a few protocols that they need to go to, so that's what we need to adhere to with the medical staff. But they are very happy."
Farrell also confirmed that Joey Carbery will be available. The out-half has trained fully since Monday.
