Johnny Sexton will be "continually assessed" as an ankle injury threatens his involvement for Leinster in Saturday's URC quarter-final clash with Glasgow Warriors (3.15pm).
The Blues skipper suffered the injury in the first half of the devastating Champions Cup final defeat to La Rochelle last Saturday.
Sexton was taken off after 62 minutes, with Leo Cullen explaining later he wanted to "freshen things up" and confirmed the ankle issue.
