Scotland head coach Gregor Townsend has recalled Magnus Bradbury as a replacement for Hamish Watson for the remainder of the World Cup campaign.
Watson played 38 minutes during the game against Ireland at International Stadium Yokohama in the opening round of the tournament before he was forced off the field with a knee injury. The 24-year-old was carried off the field on a stretcher and a scan later confirmed that he will be ruled out for the remainder of the showpiece event.
"While there is a high probability of picking up injuries during a World Cup, it's always disappointing to see someone having to head home," said Townsend.
"We feel for Hamish who had worked so hard for this opportunity and wish him well in his recovery."
Bradbury was already in Japan as a cover for Jamie Ritchie will now be officially part of the World Cup squad ahead of their game against Samoa in Kobe next month. He has played eight Tests for the Dark Blues with his last appearance coming against Georgia earlier this month and has scored three tries.
Scotland are at the bottom of Pool A following their 27-3 defeat to Ireland and will face Samoa, Russia and Japan in the remainder of the tournament.
