He has broken a bone in his foot for the second time this season
Leinster have confirmed that Jack Conan is likely to miss the rest of the season.
The powerful flanker is facing at least another month out of action during an injury-plagued campaign after breaking a bone in his foot for the second time this season.
He suffered the latest injury in training last week after he was sidelined for 10 weeks when he broke a bone in his other foot last November.
In better news for Leinster, Luke Fitzgerald, Rob Kearney and Marty Moore are all close to a return to action with Fitzgerald hoping to a play a part in this weekend's Pro12 derby against Connacht.
