Scotland have called Matt Currie, Ben Muncaster and Nathan McBeth into their squad for Saturday's Six Nations clash with Wales but Luke Crosbie and Jack Mann have been ruled out by injury.
Currie has been recalled after scoring a hat-trick for Edinburgh against Munster on Friday, having recovered from concussion.
He will be joined by club-mate Muncaster, who also started the win in Cork, and Glasgow prop McBeth.
Crosbie was replaced early in the Edinburgh game and is back at his club to undergo further assessment, while Mann suffered a head injury in Glasgow's match against Ospreys on Saturday and is undergoing World Rugby's concussion protocols.
Scotland suffered defeats to Ireland and England following their opening-weekend win against Italy, while Wales are bottom of the table after losing all three of their Six Nations matches so far.
