Johnny Sexton has been given the all clear for Leinster's Champions Cup clash against the Exeter Chiefs at the Aviva Stadium.
The Ireland out-half suffered a quad muscle injury in Sunday's win over the same opposition at Sandy Park, but was back training with the Province this morning.
Rhys Ruddock is facing a lengthy spell on the sidelines however, following the confirmation that his hamstring injury is a grade three tear.
Leinster scrum coach John Fogerty admitted today that the outlook doesn't look good for the player.
"Initial reports aren't great," he said.
"He's not going to be involved this week, or the next week, or the next week.
"He's going to see a specialist - which isn't a good sign either - a little bit later this week, and the timeframe of the injury will become clearer then."
Meanwhile, Keith Earls has returned to training with Munster.
The Limerick man suffered a hamstring injury in the build up to Ireland's November Test against South Africa and was expected to be out for two months.
Coach Johann van Graan feels he could feature in the weekend's match against Leicester at Welford Road, but it depends on his response to training.
