Leinster have announced Rob Kearney has undergone bicep surgery in a further blow to the Ireland full-back’s British and Irish Lions hopes.
The 31-year-old has been out of action since sustaining a knee injury in training prior to Ireland's game against England in the Six Nations on March 18.
Kearney required a knee operation two weeks ago on that injury and Leinster revealed this latest surgery would rule him out for "a number of weeks".
