Christchurch - Ross Kennedy has been revealed as the Crusaders' wildcard signing in their squad for next year's Vodacom Super Rugby tournament.

According to the stuff.co.nz website, Kennedy, a former junior All Black, who was on the Hurricanes and Highlanders rosters between 2003 and 2009, will return from South Africa to add depth to the Crusaders' second row stocks after internationals Brad Thorn and Chris Jack signed to play in Japan.

After playing for Hawke's Bay in the ITM Cup last year, Kennedy moved from Sydney to South Africa to represent Eastern Province Kings who had his father, Adrian, on their coaching staff. They finished runner-up in the Currie Cup First Division competition.

The 29-year-old shot to prominence six years ago with his athletic performances but struggled to maintain form because of injuries.

Now he is set to provide head coach Todd Blackadder with another locking option as he looks to ease the burden on the likes of Sam Whitelock, Tom Donnelly and Luke Romano during a Super Rugby season interrupted by the June Tests.

It is believed Kennedy's experience encouraged the Crusaders to recruit him over several rookie prospects.
