Scarlets hooker Matthew Rees returns to the Wales side for Saturday's Six Nations encounter with Ireland but skipper Ryan Jones will not be involved in Dublin.

The Scarlets struck for two tries in the opening quarter as they brought Ulster's unbeaten run in 2010 to an end and boosted their own Heineken Cup qualification hopes with a 25-8 victory at Parc y Scarlets.

Ulster's only loss in their last four matches with Scarlets in all competitions was 43-17 at Parc y Scarlets in the Magners League on 16 May 2009. Ulster won 45-24 when the two met at Ravenhill in round 5, but have never achieved a league double over the Welshmen in the same season.

Scarlets Head Coach Nigel Davies has said his side must be more clinical on Friday evening in a must win Magners League match at Parc y Scarlets against Ulster (5th March,1905 KO).

Almost half the Wales squad will be available for Magners League action this weekend.

After consultation with their broadcast partners BBC Wales, S4C and Setanta, Celtic Rugby can now confirm the dates and kick-off times for Rounds 15 and 16 of the Magners League in April.

The Round 11 Magners League game between Munster and Scarlets, originally postponed to bad weather on 10 January, has now been rearranged.

Wales coach Warren Gatland has named eight Ospreys and six Blues in his starting XV for the Six Nations clash with France this Friday.

Out-half Jonathan Sexton collected 22 points - a try, a conversion and five penalties - as he helped Leinster break clear of the Scarlets in Saturday's Magners League tussle at the RDS.

Cardiff Blues duo Gethin Jenkins and Gareth Williams and Scarlets hooker Matthew Rees have all been ruled out of Wales' Six Nations clash with France next Friday.

The Scarlets are reunited with Wales trio Martin Roberts, Jonathan Davies and recently called-up Ken Owens for their key Magners League match away at Leinster this Saturday (20th Feb) at the RDS.

The race is on, the pace is quickening and there are now only 100 days to go to the inaugural Magners League Grand Final on Saturday, May 29.

Scarlets have won their last three away games in all competitions, and have not lost on the road in the Magners League since a trip to Connacht on 30 October, however the Welsh Regions has lost on their last five visits to Ireland.

The return of Gethin Jenkins has seen Wales head coach Warren Gatland name an entire Magners League matchday 22 for this weekend's clash with Scotland.

Munster have won their last 13 home games in all competitions, whilst no Welsh team has won on Munster soil since Cardiff Blues visited Musgrave Park on 5 October 2007.

The Scarlets won away from home for the first time in this season's Magners League as second half penalties from Stephen Jones and Rhys Priestland shot them past the Newport Gwent Dragons.

Scarlets have won their last three games against Dragons, and incredibly have been victorious on four of their last five visits to Rodney Parade.

Two tries from prop Paul James proved decisive as the Ospreys made it four wins in-a-row in all competitions with a Boxing Day derby success over the Scarlets. But the Llanelli-based side did take something from the game, with flanker Johnathan Edwards' late converted try secured a losing bonus point.

Ospreys achieved a Magners League double over Scarlets last season, winning 28-19 on their only previous visit to Parc y Scarlets on 18 April.

The Scarlets' three-match home winning run was ended on Friday night as Edinburgh showed their battling qualities to come from behind and take the points, claiming two converted tries in the second half.
