Rugby briefs: Aberdeen Grammar School Aberdeen Grammar School FP have appointed Kevin Wyness as their new head coach, replacing Alex Duncan after his four years at the helm. The 48-year-old, who played for the club for 15 years, had been Duncan's forwards coach since 2010. He also had a stint coaching at Ellon and, after Aberdeen finished fifth this season, missing a British and Irish Cup spot by a solitary point, he is enthusiastic about their ability to push into title contention next season. Wyness, who will be assisted by Ali O'Connor, Colin Philips, Stuart Corsar, Rob Aloe and Steven Park in the revamped structure, said: "The coaching team and I are already preparing for the new season. We have a talented and committed group of players who have proved they can compete at the highest level - the task is to turn that potential into consistent and tangible results. Glasgow are set to unleash Fijian star Niko Matawalu on the sevens circuit this weekend and welcome back Chris Fusaro as part of a Warriors side competing in the Glasgow City Sevens Cup at Cartha Queen's Park. Matawalu and Fusaro, the openside flanker who has been out with a groin injury since December, are joined by the speedy full-back Fraser Thomson, Melrose Sevens winner Scott Wight, prop Gordon Reid and promising youngsters Murray McConnell, Andy Redmayne, Callum Reid, Jack Steele and Bruce Dick. They will be coached by Elite Development coach, Iain Monaghan, and take on Glasgow University in the first round at 1.40pm. The tournament, the finale in the Legacy Sevens Series, will also welcome teams from Munster, Saracens and domestic league and cup winners Ayr. Four Jedburgh men will take centre stage at Jed-Forest Sevens tomorrow after putting their bodies on the line in a different, and more painful way than those taking to the field. Paul Hill, Greg Nagle, Mark Burke and personal trainer Robert Reid, a former soldier who lost his left eye in an explosion in Iraq, have ridden a four-seater bike to all of the Borders" Kings of the Sevens events and this week capped their charity effort by cycling a full lap of Scotland between the Selkirk and Jed tournaments.
