Route 6'6" is aimed at sourcing and introducing new second row forwards to the game. It is anticipated that this will lead to further positional-specific screening days for other positions in the future.
Commenting on the initiative, McEntee said: "First and foremost this is about players and our clubs. We want to help introduce rugby to people of a particular height - in this case over 6ft 5in or 6ft 6in - who may or may not have played the game before.
"This initiative is open to those who have never played rugby before, as well as to those who may have given up the game for one reason or another.
"It's also open to people who currently compete in an alternative sport and who have always wanted to play rugby. In essence, if there is a will to learn, we have the technical ability to help them."
Applications are open to players between the ages of 17 and 23 to attend a free screening day at Donnybrook.
Places are limited so those interested can apply online here.
