Rugby Union: Doubts over Scots' hooker and lock

Scotland's build-up to tomorrow's international with South Africa at Murrayfield was further disrupted yesterday, with two more players in danger of missing the match through injury.

The lock Stewart Campbell and hooker Grant McKelvey were both forced to miss training with what were described as "niggling injuries" and a decision on their participation will be made today.

Campbell is struggling with a calf strain picked up after the defeat by Australia, while McKelvey has a recurrence of an Achilles tendon problem that delayed his comeback earlier this season.

The Scots are already without the long-term injured Tom Smith, two other Lions in Doddie Weir and Alan Tait as well as the winger James Craig.

The Scotland coach, Richie Dixon, said: "We've had our injury troubles this week and it is very frustrating for everyone. But we will not take chances. If they are not 100 per cent fit we won't expose them to the rigours of international rugby."

The Watsonians lock Stuart Grimes, left out of the 21 named on Thursday, took Campbell's place as the squad ran through their training drills yesterday and he would step in for his second appearance after being a half-time replacement against Australia.

If McKelvey has to withdraw, Gordon Bulloch - the captain of both West of Scotland and Glasgow District - will step up from the bench for his international debut.

The South Africa stand-off, Henry Honiball, has been ruled out because of a knee injury he sustained against England.

Honiball, who has played in all four Tests on tour, will be replaced by the Free State No 10, Jannie de Beer, who made his debut against the Lions earlier in the year and now has six caps to his name.
