Lawson in as Scotland call on Falcons trio
Lawson, 36, won the last of his 46 Scotland caps in November 2014 but has gone on to make 102 competitive appearances during his four and a half seasons with the Falcons.
Prop-forward Welsh is also named in head coach Gregor Townsend’s 40-man group, the Glaswegian having trained with Scotland during the autumn tests as looks to add to his tally of 11 caps, the last of which came during the 2015 Rugby World Cup.
Centre Harris is the third Falcons player named in Scotland’s squad, the 27-year-old making his test debut against Samoa in November.
Newcastle Falcons director of rugby Dean Richards said: “It’s great that more of our players are beginning to be recognised at international level for the consistently strong performances they have been showing for us over a long period of time.
“For Scott in particular it is fantastic to know he is very much on the radar a few years since his last involvement, but I’m delighted for all three boys and I hope they go on to feature for Scotland during the Six Nations games when they come round.”
Scotland open their campaign away to Wales on Saturday February 3.
