Frank Hadden has dismissed suggestions that Nathan Hines' return to the Scotland set-up threatens to disrupt their rebuilt team spirit.
Nathan Hines is in line to face England
And he believes that the Perpignan lock could prove a big plus against England.
"He is a very gifted footballer with tremendous handling skills and being 19 stones is a bonus too against a big English side," said the Scotland coach.
"The players and coaches are happy to have been able to call up someone of Nathan's ability."
Hines had made himself unavailable for selection under previous Scotland coach Matt Williams but was recalled after suspension to Scott Murray.
"He was with Edinburgh for eight years before heading for France, so I've known Nathan Hines for a long time," said Hadden.
"I've spoken to Nathan ever since he moved to France and he made it clear that he had not retired from international rugby.
"There were certain circumstances that made it difficult for him, but those have been cleared now."
Hines could be in line for a place in Hadden's side for the Calcutta Cup match, having not played for his country since the Six Nations defeat at Twickenham in 2005.
The 29-year-old said: "It was my last game for Scotland and wasn't a good time for me.
"To play against England and play well would mean a lot.
"It was very oppressive under Matt and it's a lot more enjoyable now.
"The lads have smiles on their faces in training and that's probably the biggest change Frank has brought to the team.
"It feels like, and not just for me, there's been a weight lifted off everyone's shoulders.
"I don't see any problems with me coming back as I've know everyone in the squad for some time."
