Swinson – who earned the most recent of his 38 Scotland caps in the 2018 win over Argentina in Resistencia – will provide training cover for Skinner, who sustained a hamstring injury in the national team’s 17-14 win over France at BT Murrayfield on Saturday.

Skinner had the muscle scanned at Spire Murrayfield Hospital on the evening of the match, with the time taken to recover deemed insufficient to play a meaningful part in Scotland’s Rugby World Cup 2019 campaign.
