Sexton's fate in Racing's hands as Wales lose James for Ireland clash
Johnny Sexton has returned to France where he will be assessed by medics at Racing Metro before a decision is taken on whether he will play against Grenoble on Saturday.
The IRFU yesterday released a medical bulletin that described the hamstring strain the Ireland fly-half suffered during Sunday's win over England as "minor" and he should be fit in time to face Wales on Saturday week.
It is believed that one of the underlying causes of his pulling up after converting Robbie Henshaw's kick is that he has played three games on successive weekends after coming back from a 12-week lay-off. Speaking after his comeback game against France, the player himself suggested that he would be rested for this weekend's club game to help manage his workload.
He will not link up with the rest of the squad when they assemble in Belfast for a 24-hour camp tomorrow, while Sean O'Brien and Jared Payne are undergoing return-to-play protocols after suffering concussions in Sunday's 19-9 win which sets Ireland up for a Grand Slam tilt.
If they come through their various tests without suffering further symptoms, they should be able to train fully at the start of next week, while there was no update on Jamie Heaslip's condition as he attempts to recover in time for the Millennium Stadium meeting.
Warren Gatland has been dealt a blow with a thumb injury ruling out loosehead prop Paul James. Captain Sam Warburton and out-half Dan Biggar are expected to return to training later this week having suffered less serious injuries against France.
