Scotland will go into the A International against England at Newcastle on Friday night without Paul Johnstone, their outstanding loosehead prop, but the side will be strengthened by the return of Doddie Weir after his Tetley Cup victory, and the presence of senior cap Jason White.

Johnstone, who represented Zimbabwe at senior level before opting for Scotland, was said to have cited ''personal reasons'' for his non-availability.

Last summer, Johnstone made himself unavailable for the

Scotland tour to New Zealand because of worries over the worsening situation in Zimbabwe, where his family farm.

Team manager Rob Flockhart declined to go into detail but added that his absence is ''very disappointing''.

The upside, as coach Graham Hogg pointed out, is that Allan Jacobsen will come into the side. ''He needs to be playing at this level,'' added Hogg.

The knock-on effect is that Willie Anderson, the erstwhile Caley Reds player, now back playing with Kirkcaldy, has been drafted into the squad. Anderson shared in the Scots' grand slam at A level three seasons ago and despite no longer playing in the professional game, he is still highly regarded by the A team management.

''He's a player who's been there before at this level. From our point of view, we need a player who can scrum. Willie can certainly do that,'' said Hogg.

The return of Weir will be important, not least because the former Melrose lock will be playing at his current home ground, Kingston Park, but more important for the A squad is the presence Weir brings.

''Doddie was a very important part of our preparation for the France game,'' said Hogg.

Weir's inclusion means that Steve Griffiths will be back on the bench. It is hard luck on the Caley Reds lock, who had a very good game against Wales A.

The Scotland A management will finalise their team tomorrow but the expectation that the changes will be minimal, with Weir coming in for Griffiths and White being slotted in as blindside flanker, with Donnie Mackinnon moving to No.8.

Meanwhile, there are a number of changes in the Scotland Under-21 team for the match against England in Warwickshire. In the backs, Andy Henderson returns at centre after missing the Wales game because of concussion, with the consequential effect that Simon Webster moves from centre to wing, and David Frame from wing to full back.

The other change in the backs is at scrum half, where Calum Cusiter moves ahead of David Irving, the latter seems to be paying the price for playing outwith the Premiership. ''There is very little to chooses between them,'' said team manager Roy Laidlaw.

He added: ''Calum is playing at Premiership One level and is sharper.''

There are a number of changes in the forwards, two of them in the front row where Euan Murray comes in at the expense of Eric Milligan, while Bruce Douglas switches to the other side of the scrum. Squads:
