Ulster wing Simon Danielli returns to the Scotland training squad for the for the forthcoming Six Nations Championships after missing the World Cup through injury.

His provincial teammate Rob Dewey has been invited to attend the international training sessions despite being injured as the Scots begin their preparations in earnest.

Coach Frank Hadden has included six uncapped players — Edinburgh backs Ben Cairns, Nick De Luca and Calum MacRae, Glasgow wing Thom Evans and prop Moray Low and Edinburgh back-row forward Ross Rennie - in the 35-man squad and was keen to highlight the strength in depth available to him this year.

Hadden said: "I continue to be impressed with the competition for places in the squad. A number of players have maintained their good form from the World Cup but they are going to be pushed extremely hard by some of our young, up and coming talent in the next few weeks."

Omitted from the squad since the World Cup are lock Scott Murray, prop Craig Smith and hooker Scott Lawson.

Hadden insists there will be opportunities for the that trio, and other contenders outside the training squad, to push for places.

However, one player who has ruled himself out is centre Marcus Di Rollo.

His omission follows his own commitment to make himself available exclusively for his French club, Toulouse, during this season's championship, but he vowed to compete for his Scotland place again in the future.

Di Rollo said: "Making myself unavailable for Scotland for this year's Six Nations Championship was not a decision I took lightly.

"After a period of injury and transition from Scotland to France I felt it would be beneficial for my game to take some time to settle into my new club."
