All the team news ahead of this weekend’s round of Six Nations fixtures.

Ireland v Italy(Aviva Stadium, Saturday, 1.30pm): Declan Kidney has named an unchanged starting line-up for the clash with Italy at the Aviva Stadium. Jonathan Sexton has made a full recovery from the thigh muscle injury sustained before the postponed match against France and starts at uothalf. The fixture launches a gruelling schedule of four games in as many weeks as Ireland suffer the consequences of the aborted showdown at the Stade de France 10 days ago.

Kidney has acknowledged there will be an issue regarding match rustiness given the starting line-up have played only once over the last four weekends � and in Keith Earls's case not at all � while Sexton has played just once in five weeks. Training has thus been tweaked, with some extra contact work in 15-a-side match situations in last week's curtailed one-day get-together and again yesterday.

Italy coach Jacques Brunel has made four changes with Tobias Botes coming in at outhalf, thus earning his first Azzurri start. Kristopher Burton relegated to the bench alongside Gonzalo Canale, whose place at number 12 is taken by Alberto Sgarbi.

Benetton Treviso loosehead prop Michele Rizzo will make his Six Nations debut in Dublin, replacing veteran Andrea Lo Cicero, who drops to the bench. Lorenzo Cittadini will make his first appearance in this year's tournament replacing injured Leicester prop Martin Castrogiovanni. Castrogiovanni will miss the rest of the tournament after sustaining a fractured rib in the defeat by England.

England v Wales(Twickenham, Saturday, 4pm)

Interim England head coach Stuart Lancaster has made four changes to his line-up for the clash with Wales. As expected Geoff Parling, Ben Morgan and Lee Dickson are handed their first starts for England, while Manu Tuilagi comes into the centres.

Parling will line-up in the secondrow along Mouritz Botha, with Tom Palmer having been released from the training squad on Tuesday.

Scarlets number eight Morgan and Northampton scrumhalf Lee Dickson are rewarded for impressive cameos off the bench in the games against Italy and Scotland, with Phil Dowson and Ben Youngs making way. Tuilagi's inclusion comes after Charlie Hodgson was ruled out with a finger injury - so Owen Farrell moves to outhalf.

Sam Warburton has recovered from injury and will captain Wales when they bid for the Triple Crown. The Cardiff Blues flanker missed Wales' 27-13 victory over Scotland nine days ago due to a thigh problem that forced him off at half-time against Ireland in Dublin a week earlier.

But Warburton is now back to lead a team showing three changes from the one that saw off Scotland. The skipper replaces Aaron Shingler in the back row, while fit-again lock Alun-Wyn Jones is preferred to Ryan Jones and hooker Ken Owens gains his first Wales start. Owens, who made his Test debut during last autumn's World Cup campaign, is promoted off the bench as calf muscle strains sideline both Huw Bennett and Matthew Rees.

England:B Foden (Northampton Saints); C Ashton (Northampton Saints), M Tuilagi (Leicester Tigers), B Barritt (Saracens), D Strettle (Saracens); O Farrell (Saracens), L Dickson (Northampton Saints); A Corbisiero (London Irish), D Hartley (Northampton Saints), D Cole (Leicester Tigers), M Botha (Saracens), G Parling (Leicester Tigers), T Croft (Leicester Tigers), C Robshaw (Harlequins, capt), B Morgan (Scarlets). Replacements:R Webber (London Wasps), M Stevens (Saracens), C Lawes (Northampton Saints), P Dowson (Northampton Saints), B Youngs (Leicester Tigers), T Flood (Leicester Tigers), M Brown (Harlequins).

Wales:L Halfpenny (Cardiff Blues); A Cuthbert (Cardiff Blues), J Davies (Scarlets), J Roberts (Cardiff Blues), G North (Scarlets); R Priestland (Scarlets), M Phillips (Bayonne); G Jenkins (Cardiff Blues), K Owens (Scarlets), A Jones (Ospreys), A-W Jones (Ospreys), I Evans (Ospreys), D Lydiate (Newport Gwent Dragons), S Warburton (Cardiff Blues, capt), T Faletau (Newport Gwent Dragons). Replacements:R Hibbard (Ospreys), P James (Ospreys), R Jones (Ospreys), J Tipuric (Ospreys), L Williams (Cardiff Blues), J Hook (Perpignan), S Williams (Scarlets).

Scotland v France(Murrayfield, Sunday, 3pm)

Andy Robinson has made four changes in personnel for the clash with France at Murrayfield. Stuart Hogg is to make his first test start at fullback, with his Glasgow Warriors team-mates John Barclay and Graeme Morrison recalled at blindside flanker and inside centre, respectively.

Mike Blair has been called up at scrum-half, with two positional switches — Sean Lamont moving from inside to outside centre and Rory Lamont from full-back to the right wing. Two of the changes were enforced, with Barclay replacing Alasdair Strokosch, who has been ruled out of the tournament with a fractured hand, and wing Max Evans unavailable for selection due to an ankle injury.

France coach Philippe Saint-Andre has named the same side that had been due to play Ireland 10 days ago. Saint-Andre has chosen to go with the same 15 that had been set to take to the field against Ireland on February 11th, only for the game to be postponed due to freezing conditions in Paris.

While Scotland present a different challenge to Ireland, Saint-Andre felt it was only fair to give the starting XV their chance.

Soctland:S Hogg (Glasgow Warriors); R Lamont (Glasgow Warriors), S Lamont (Scarlets), G Morrison (Glasgow Warriors), L Jones (Edinburgh); G Laidlaw (Edinburgh), M Blair (Edinburgh); A Jacobsen (Edinburgh), R Ford (capt, Edinburgh), G Cross (Edinburgh), R Gray (Glasgow Warriors), J Hamilton (Gloucester), J Barclay (Glasgow Warriors), R Rennie (Edinburgh), D Denton (Edinburgh). Replacements:S Lawson (Gloucester), E Kalman (Glasgow Warriors), A Kellock (Glasgow Warriors), R Vernon (Sale Sharks), C Cusiter (Glasgow Warriors), D Weir (Glasgow Warriors), N De Luca (Edinburgh).
