Scotland lock Grant Gilchrist ruled out of World Cup

Scotland lock Grant Gilchrist has been ruled out of the World Cup with a groin injury, Scottish Rugby has announced.

Gilchrist suffered a groin injury in the first-half of Scotland's clash with the USA on Sunday, a game they went on to win 39-16.

Scotland are yet to name a replacement for the 25-year-old, who plays his club rugby for Edinburgh.

Head coach Vern Cotter is still sweating on the fitness of influential playmaker Finn Russell ahead of next Saturday's crucial Pool B clash with South Africa after he was carried off during Sunday's game.

An SRU statement said: "Scotland second-row Grant Gilchrist has been ruled out of the national team's Rugby World Cup 2015 campaign with a groin injury.

"Gilchrist sustained the soft tissue damage in the 19th minute of the national team's 39-16 win over USA, with the recovery period expected to extend beyond the competition."

This is just the latest injury setback to beset Gilchrist, 25. The Edinburgh forward was due to skipper the Dark Blues during last year's autumn Tests but just a week after being appointed suffered an arm injury playing in a European Challenge Cup match in France that ruled him out for nine months.

The Scots have plenty of strength in depth in the second row, with Richie Gray, Jonny Gray and Tim Swinson already in the squad.

However, Jim Hamilton, who would have been one of Cotter's likely first reserves, announced his international retirement after missing out on the original 31-man squad selected for England 2015.

What will worry Cotter more is the knock picked up by Russell.

The Glasgow stand-off has proven to be the Scots' talisman with his inventive style of play.

Duncan Weir replaced Russell after he was injured in the 60th minute against the States and scored the fifth and final try but Cotter will hope to have his first-choice 10 fit to face the Boks in Newcastle this weekend as they look to clinch a quarter-final slot.

The SRU statement added: "Finn Russell has sustained an inversion injury to his ankle, which will require further care and assessment.

"A number of other players will require the ongoing care of the national medical team however these are not considered an immediate concern."
