Swinson gears up for cup clash
Glasgow forward Tim Swinson insists there will be no old pals' act with his Scotland colleagues as the Warriors look to retain the 1872 Cup.
The Scotstoun side welcome Edinburgh to the west coast on New Year's Day looking to protect the four-point lead secured by their Boxing Day derby success at Murrayfield.
But with the RBS 6 Nations to come just a few weeks into 2014, the match will see potential Scotland team-mates going head to head.
Second-rower Swinson - capped three times for the Scots - said: "It is strange playing the Edinburgh guys. We were all living together for a few weeks during the November Tests and now a month later we are playing against them in these crucial matches.
"And then next month, we will be all together again for the start of the Six Nations.
"That is what professional sport is all about and a lot of the guys in both sides have been through this before. That happens.
"But really we have to focus on our own team and winning our own individual battles."
Glasgow head coach Gregor Townsend pushed British and Irish Lion Stuart Hogg forward from full-back to centre last week and watched as the ploy succeeded when he scored the decisive try in the 20-16 triumph.
But Hogg will revert back to number 15 for the second leg with Edinburgh, which also doubles as a RaboDirect PRO12 fixture, after wing Tommy Seymour was ruled out with both head and knee injuries. Sean Maitland moves from full-back to the right flank, while Sean Lamont returns on the opposite side having been out of action since November with an ankle injury.
Byron McGuigan and Alex Dunbar form a new centre partnership, while Ruaridh Jackson and Henry Pyrgos come into the side at fly-half and scrum-half respectively.
In the forwards Ryan Grant continues at loosehead, with Dougie Hall coming in for Pat MacArthur at hooker and Ed Kalman replacing Jon Welsh at tighthead.
In the back row Rob Harley continues on the blindside, Chris Fusaro comes in at openside and captains the side, while Josh Strauss replaces Ryan Wilson at number eight.
But Townsend insists the eight personnel changes to his line-up will not leave Glasgow - who sit fourth in the PRO12, 11 points ahead of the seventh-placed Gunners - detrimentally weakened.
He said: "We have got a strong squad. These games are not only important to our standing in the league and our supporters, but to our players as well and I want to give them the opportunity to play in them.
"So even though we have made a few changes, we still have a strong side."
