The former Wallabies utility Cameron Shepherd's rugby career is in limbo after English Premiership club Northampton tore up his new contract on medical advice.
The 28-year-old fullback come winger was due to join the Saints on a three-year deal this month after seven seasons with Super Rugby team the Western Force.
But the Australian's arrival was subject to several conditions and, on advice from Northampton's medical team, the club cancelled Shepherd's contract.
Shepherd debuted for the NSW Waratahs as a 20-year-old and won the last of his nine caps for the Wallabies in 2010.
He has spent long periods on the sidelines in recent seasons, with groin and wrist injuries restricting him to just two games for the Force in 2012.
