LONDON-bound Lynsey Sharp will pull on a Scotland vest in Cardiff next week.
The European Championship silver medallist won't race in the 800 metres at the AVIVA Grand Prix in London this weekend.
Hurdler Eilidh Child and Eilish McColgan are on the start lists for Crystal Palace – with the latter taking on a 5000m rather than the steeplechase for which she has been picked for the Olympics.
Sharp and coach Dave Sunderland preferred to focus on training this week and now she will run a 400m leg for Scotland in a relay outing next Wednesday in Wales.
"There was an option of competing in the Diamond League in Monaco on July 20 instead of Crystal Palace, but after talking to my coach we felt this was the best schedule for me," said Lynsey.
"I was at the Olympic trials in Birmingham and then straight into the Europeans in Helsinki and needed a bit of training time.
"Scotland women had a great 4x400m relay effort when winning at the Loughborough International not so long ago and everyone in that team is involved for Wales except Eilidh Child."
Welsh Athletics are staging the international meeting next week with a number of athletes making their preparations for London.
Scotland will enter Under-20 teams as well as relay squads for the 4x400m into next week's meeting including Tom Holligan (Edinburgh AC) and Kathryn Christie (Banchory and Stonehaven).
ICE HOCKEY: Braehead Clan have captured the signing of Fife Flyers goaltender Garret Zemlak that will leave the Purple legions confident about next season.

Zemlak said: "We will do whatever it takes, and really work hard as a team, to bring a first championship to this club."
