Wales have left George North out of their team to take on Scotland in round two of the Six Nations this weekend.
The winger played on despite two blows to the head in last Friday's defeat by England in Cardiff, and coach Warren Gatland says they have decided to give him an "extended recovery period".
Liam Williams will start in North's place on Sunday, with Scott Williams among the replacements.
