Brown back as Scotland shuffle pack for France
Scotland's Kelly Brown leads his team from the pitch at the end of the international rugby union test match between Scotland and Australia at the Murrayfield Stadium in Edinburgh on November 23, 2013 - by Ian Macnicol
The Saracens flanker was overlooked for Scotland's last two games -- a 20-0 home loss to England and a last-gasp 21-20 victory over in Italy in Rome -- but returns for his side's final home game of the tournament.
Brown replaces Glasgow's Chris Fusaro, while Geoff Cross and David Denton also come into the pack in place of Moray Low and Ryan Wilson.
Explaining the changes to his pack, Johnson said: "I think Saturday is a game that will really suit Kelly. Unlike other sides in the competition, France play above the ground a bit and there will be a lot of mauling.
"I think the pitch suits Kelly too and I've picked a side that can win the game and that's most important.
"The other back-row change is slightly enforced as Ryan Wilson has not been well at the start of this week with a tonsillitis bug.
"It was important we were not hampered in our training, so Dents (Denton) comes straight in. Geoff did really well when he came on against Italy and it's right that he should start this week."
Fusaro and tighthead prop Low were both left out of the match-day squad, while Wilson was named on the bench.
Johnson has kept faith with the backs that started in the dramatic defeat of Italy, which was secured by a drop-goal from Duncan Weir 10 seconds from time.
Beaten 27-6 by Wales in their last game, France have a number of injury concerns ahead of Saturday's game, but Johnson believes that they have the strength in depth to cope.
"Whatever side France put out will be a good one," he said. "They have proven over the years that they are a great rugby nation so whatever side comes to Edinburgh, we know we'll have to be at our best."
France are currently level on four points with Ireland, England and Wales in the Six Nations standings, with Scotland two points back in fifth place.
