Perth - South Africa-born flank Chris Alcock has switched Super Rugby sides moving to the Force from the Waratahs.
The Force said Wednesday that the 24-year-old Alcock, born in Durban, had signed a two-year deal.
The openside flank played 25 matches for the Waratahs since making his provincial debut against the Cheetahs two years ago, after he was taken from Sydney grade rugby for the beginning of the 2010 season.
Alcock, who played 12 matches in 2012, starting in the No 7 jersey for the bulk of the season, follows former Waratahs' coach Michael Foley west to Perth for the 2013 season.
