Scotland interim coach Scott Johnson has delayed naming his side for Saturday's Six Nations clash with Wales due to a number of injury concerns.
Johnson will announce the starting XV on Thursday as the Scots prepare for the match in Cardiff.
Wingers Tommy Seymour and Max Evans are both expected to undergo late fitness tests, but Ryan Wilson and Alasdair Strokosch have returned to the squad.
Scotland travel to the Millennium Stadium having lost their penultimate game of the competition to France last weekend.
