Rugby - Arnold dropped from Wallabies bench

BUENOS AIRES (Reuters) - Lock Rory Arnold has been dropped from Australia's matchday squad after coach Michael Cheika finalised his bench ahead of the Wallabies' final Ruby Championship test against Argentina later on Saturday.

Cheika has gone for a five-three split of forwards and backs on the bench for the match in Salta, as the Wallabies look for a win to avoid the wooden spoon.

They have not finished bottom of the southern hemisphere tournament since 2009 when it was the Tri-Nations. The competition expanded to the Rugby Championship when Argentina joined in 2012.

New Zealand sealed their third successive title with victory over Argentina last week.

Team: 15-Dane Haylett-Petty, 14-Israel Folau, 13-Reece Hodge, 12-Kurtley Beale, 11-Marika Koroibete, 10-Bernard Foley, 9-Will Genia, 8-David Pocock, 7-Michael Hooper (captain), 6-Ned Hanigan, 5-Adam Coleman, 4-Izack Rodda, 3-Taniela Tupou, 2-Folau Faingaa, 1-Scott Sio.

Replacements: 16-Tolu Latu, 17-Sekope Kepu, 18-Allan Alaalatoa, 19-Rob Simmons, 20-Caleb Timu, 21-Nick Phipps, 22-Matt Toomua, 23-Tom Banks
