UPDATE 2-Rugby-All Blacks drop cornerstone prop Franks for World Cup

All Blacks coach Steve Hansen dropped a major bombshell in his World Cup squad on Wednesday, leaving out Owen Franks and selecting more mobile props as he signaled an intent to play an up-tempo game in Japan. Franks has been a cornerstone of the All Blacks scrum since he made his debut as a raw 21-year-old and was a key member of the squads that won the last two World Cups.

The 31-year-old tighthead, who has played 108 tests, suffered a shoulder injury that kept him out of much of Super Rugby this year but returned to the national side for the Rugby Championship. He was dropped for the Bledisloe Cup clash against Australia at Eden Park, however, and Nepo Laulala seized his opportunity to usurp Franks with an impressive scrummaging display and strong work around the field.

Lock Brodie Retallick was also included in the 31-man squad despite suffering a dislocated shoulder against South Africa last month, as was midfield back Ryan Crotty, who has been out of action for two months with a broken thumb. Hansen told reporters in Auckland that he did not expect Retallick to play in the pool phase. Patrick Tuipulotu was named as the fourth lock with Retallick, Sam Whitelock and Scott Barrett.

Rookie loose forward Luke Jacobson was included after Liam Squire made himself unavailable earlier this year and there was also a place for Brad Weber as the third scrumhalf. Rookie wingers George Bridge and Sevu Reece were also selected after strong performances in the 36-0 victory over Australia when Hansen dropped veteran Ben Smith and Rieko Ioane after some sub-par performances.

Both Smith, who is leaving for France after the tournament, and Ioane were named along with the versatile Jordie Barrett, who can play across the backline. Flyhalf Richie Mo'unga, who injured his shoulder against the Wallabies, was given the all-clear and is expected to resume his dual playmaking role with Beauden Barrett at the tournament.

The pair are the only flyhalves named in the squad, although Barrett has played fullback under the dual playmaker system. The Barretts are the first trio of brothers to be included in a New Zealand World Cup squad.

The All Blacks open their campaign on Sept. 21 against traditional foes South Africa in Yokohama, with the loser of the Pool B clash likely to face Ireland in the quarter-finals.
