Wales coach Warren Gatland has been forced into a late change ahead of their clash with South Africa tomorrow after Gavin Henson failed a fitness test on an Achilles injury.

The Ospreys centre, who took only a limited part in training this week, has not played for Wales since last season's Grand Slam-clinching victory over France at Cardiff and now makes way for Cardiff Blues centre Tom Shanklin.

With Henson out, Jamie Roberts moves to inside centre, with Shanklin wearing the number 13 shirt and Henson's Ospreys colleague Andrew Bishop promoted to the bench.

Henson watched from the sidelines as Wales went through their final training session at the Millennium Stadium this afternoon before the Wales camp confirmed his withdrawal.
