Glamorgan Wanderers flanker Navidi and Pontypridd scrum half Downes are members of the leadership group within the Under 20 squad and have started both of the side's games so far in the Under 20 Six Nations Championship against England and Scotland.

Davies said, "We are very pleased with the leadership shown by Dan Watchurst and Matthew Jarvis in the first two games and we always planned to change things around in order to develop leadership and experience within the squad.

"Josh came into the squad last season as a newcomer to the system and has developed extremely well. He captained the side for 40 minutes against Exeter at our recent training camp and did very well. He has been given a chance by the Blues and at international level with us and I'm confident he and Rhys Downes are more than capable of stepping up to the plate on Friday afternoon."

Davies has made only one change and one positional to his side, with Toby Faletau making his first Six Nations start at no 8 and Morgan Allen moving to the blindside. Faletau is the son of Kuli Faletau, Tonga's most capped forward who played second row for Ebbw Vale.

Phil Davies added, "We are expecting a physical challenge from France and the back row selection, along with picking five forwards on the bench reflects that. We want to win every game but we also want to maximise the potential of every player within our squad. Around 30 players have been involved with us so far this season which bodes well for the Junior World Championship in June and looking ahead at next season.

"We've certainly seen a marked improvement in performance levels since the start of the season and a lot of that is down to the cooperation and support we've received from the Regions and Premiership clubs. We want to continue to raise the bar, starting with France on Friday. We're playing on Friday afternoon in Cardiff city centre so we're hoping Welsh fans will give us their support before the RBS 6 Nations game at 8pm."
