Wales coach Warren Gatland will be without Samson Lee for Sunday's Six Nations clash with Scotland.
The 22-year-old has failed to pass concussion protocol ahead of the trip to Murrayfield, with the Scarlets player being replaced in the side by Aaron Jarvis.
Scott Andrews has been introduced into the 23-man squad as a replacement for Jarvis on the bench.
Wales will be hoping to record their first win of the competition after falling to a 21-16 defeat to England last Friday.
Wales team to face Scotland:
Leigh Halfpenny, Alex Cuthbert, Jonathan Davies, Jamie Roberts, Liam Williams, Dan Biggar, Rhys Webb, Gethin Jenkins, Richard Hibbard, Aaron Jarvis, Jake Ball, Alun Wyn Jones, Dan Lydiate, Sam Warburton, Taulupe Faletau
Replacements: Scott Baldwin, Paul James, Scott Andrews, Luke Charteris, Justin Tipuric, Mike Phillips, Rhys Priestland, Scott Williams
