Leinster are playing down reports linking them to All Blacks second-row Brad Thorn.
Thorn, who will be 37 next month, is currently in the middle of a six-month deal with Japanese club Fukuoka Sanix Blues.
After being rocked by an injury to captain Leo Cullen, which will rule him out for up to two months, and the departure of South African Steven Sykes, coach Joe Schmidt is desperate for second-row cover.
Any short-term deal to cover the latter stages of the Heinken Cup would have to be approved by the IRFU.
"It's purely speculation," said a Leinster spokesperson. "We are looking at players in that position at the moment, but we do not comment on specific targets."
