Scotland prop Jon Welsh will miss the rest of the Six Nations after suffering a broken hand in Sunday's loss to Wales.
The Glasgow Warriors tighthead came on as a second-half replacement for the Scots but was injured in the dying seconds of the game at Murrayfield.
He will undergo surgery later this week, and the Scottish Rugby Union confirmed that he was not expected back before the end of the competition.
Welsh came into the competition as third choice for the Scots, but featured on Sunday because of Euan Murray's absence for religious reasons.
With Scotland not set to play any further Six Nations games on a Saturday, Vern Cotter will only require a replacement if Murray or Geoff Cross get injured in the coming weeks.
Welsh was not the only Scottish player to require medical attention after the game, with both Gordon Reid and Sam Hidalgo-Clyne being treated for potential concussions.
Finally Richie Gray, who was forced off in the second half with an arm injury, will have a scan to see if there is any serious damage.
