Gregor Townsend has added four players to his squad ahead of Saturday's trip to Rome to face Italy in the penultimate Six Nations fixture of the season. 

The Scotland head coach has lost Sione Tuipulotu, WP Nel and Alex Craig from his squad and he's brought in Edinburgh pair Javan Sebastian and Marshall Sykes as well as Glasgow Warriors' Jamie Dobie and his soon-to-be Glasgow team-mate, prop Rory Sutherland. 

Scrum half Dobie is fresh off the back of signing a new contract with Warriors and admitted he was desperate to get back into the international set up.

None of the players selected are direct replacements for Tuipulotu, with Sebastian and Sutherland coming in to cover the front row and Sykes adding an extra option in the second row.

Townsend will have a decision to make on who partners Huw Jones in the centres on Saturday, but Cameron Redpath, Stafford McDowall and Rory Hutchinson as options to cover the injury of Tuipulotu. 

Glasgow head coach Franco Smith confirmed the centre would be out for between eight to 12 weeks before Saturday's win over Benetton in the URC but he is likely to return for the league run-in, as is Richie Gray - who suffered a bicep injury during the Six Nations opener against Wales. 

Scotland face Italy in Rome on Saturday afternoon and will be hoping to get a result that can place some pressure on Ireland before their game against England and provide a potential opportunity to take the Championship into the final day in Dublin on March 16.
