Scrum-half Chris Cusiter, 32, was ruled out of Vern Cotter’s initial squad with a knee injury, but came through 80 minutes in Sale Sharks’ 14-10 win over Saracens on Saturday.
Exeter Chiefs tighthead prop Moray Low, 30, has also been called up as a replacement for the injured Jon Welsh (hand), despite having no game time since being stretchered off in the Chiefs’ 28-26 defeat at London Irish in January.
Cotter’s back-row injury problems have also eased with the availability of Edinburgh’s David Denton, who has recovered from a calf tear, and Glasgow Warriors number eight Adam Ashe, who has recovered from a neck injury.
Warriors loosehead prop Alex Allan has also been called up as a replacement for injured club team-mate Gordon Reid (knee), who lasted all just three minutes after coming off the bench in the 26-23 defeat to Wales at BT Murrayfield earlier this month.
Cotter had earlier called up Warriors lock Tim Swinson as cover for Castres’ Richie Gray, who was taken off with an arm injury against Wales.
Scotland have lost their opening two rounds of this year’s Six Nations, despite impressing in phases and having plenty of chances to win, and they welcome the Azzurri to Edinburgh knowing they must win.
The match is Scotland’s only home match in this championship not to sell out, but the Dark Blues will be spurred on by the country’s armed forces with 1,000 free tickets made available through Tickets for Troops.
Chris Fusaro (ankle), Grant Gilchrist (arm), Richie Gray (arm), Sam Hidalgo-Clyne (subject to concussion return-to-play protocols), Ruaridh Jackson (knee), Sean Maitland (shoulder), Henry Pyrgos (knee), Gordon Reid (knee), Tommy Seymour (hip), Duncan Taylor (returning from hamstring), Duncan Weir (arm), Jon Welsh (hand).
