Friday

Ireland's Sam Bennett will be in action again for Stage 6 of the prestigious race.

Friday's race will be a 25.5km course from Barbentane to Barbentane, with the Carrick-on-Suir native looking to add to the stage win he picked up on Tuesday.

Soccer - SSE Airtricity Premier Division

Shamrock Rovers are looking to stay on top

There's five key fixtures down for decision this evening, with current table leaders Shamrock Rovers among those in action. They welcome Sligo Rovers to Tallaght Stadium for an 8pm kick-off.

Bohemians are closely behind in second place and they will be hoping to keep up the chase when they take on Cork City, while Dundalk will travel to the Ryan McBride Brandywell Stadium for a meeting with Derry City.

The other games will see UCD take on Finn Harps, while Waterford welcome St Patrick's Athletic.

Rugby - U20 Six Nations

Will there be a Grand Slam for the U20's?

Ireland are already U20 Six Nations champions following their victory over France, but they will hoping to collect a Grand Slam title when they take on Wales. Kick-off for that match will be at 7.05pm and it is live on RTÉ2.

Italy will finish out their campaign against France at home while England and Scotland will be in action in the other Six Nations game on Friday evening.

Cricket - Afghan Test for Ireland

Today sees the first day of the Test match against Afghanistan at the Rajiv Gandhi International Cricket Stadium in India.

Ireland are currently six weeks into their tour of Oman and India but after a series of T20 games and One Day Internationals, the Test match with Afghanistan is a big step up.

This will be Ireland’s ninth and final game of their tour.

To start with, the Irish team will have at least four - and up to eight - players for whom this is their Test bow. For all but Boyd Rankin it will be their first Test overseas, and in conditions about as alien to those in which they made their debut as it is possible to get.

Golf - Players Championship

Ponte Vedra Beach, Florida is the venue for the 38th edition of an even that some refer to as the 'fifth major'

Rory McIlroy, Shane Lowry and Seamus Power are the Irish players in action. Continues until Sunday.

Saturday

Rugby - Six Nations

The Six Nations finale is upon us and winning the championship looks to be beyond Ireland at this point. Still, they could snatch it if results go their way.

Joe Schmidt's side travel to the Principality Stadium to face a Welsh side who are chasing a Grand Slam title.

Victory there is the optimum task for Ireland, while they will also need Scotland to do them a favour by defeating England in Twickenham.

However, Scotland haven't defeated England at Twickenham since 1983, meaning Ireland's chances of finishing as champions seems improbable. 

GAA - Allianz Hurling and Football Leagues

Galway and Wexford are battling for a place in the semi-finals

Semi-final places are up for grabs in the hurling league this weekend.

Galway welcome Wexford to Pearse Stadium, Clare travel to face Waterford while Tipperary and Dublin are also in contention for a place in the final four of the competition.

Kilkenny and Cork will feature in the Division 1 relegation play-off, but since the league will be restructured next year, it's a relatively meaningless tie. It will merely decide which group they will be placed in for 2019.

You can fixture details here.

There's also a host of Allianz football league matches to look forward to, including four games in the top tier.

Monaghan and Cavan will do battle in Clones where a result will be crucial for either side to keep their hopes of staying in Division 1 alive. Roscommon and Galway are also in action while Kerry will be looking to keep their winning record intact when they host Mayo in the evening.

Dublin and Tyrone will converge on Croke Park in the other Division 1 game on Saturday.

GAA - All-Ireland club finals

Corofin are looking to defend their All-Ireland crown this weekend

St Patrick's Day sees the club hurling and football seasons reach their pinnacle. The reigning football champions Corofin (Galway) are back in the final and will take on the 2017 champions Dr Crokes of Kerry in what should be a cracking tie.

The sides met two years ago when Dr Crokes scored a comfortable win en route to their eventual triumph.

"We know Crokes are an incredible team," Corofin's Martin Farragher told RTÉ Sport this week ahead of the Croke Park showdown, "they have some serious players like Johnny Buckley, Gavin White and Tony Brosnan. These are all top players.

"They'll take some stopping on the big stage." 

Kilkenny's Ballyhale Shamrocks and Galway champions St Thomas' will contest the hurling decider.

This is a battle of the heavyweights in club hurling, and an epic encounter is expected to unfold in Croke Park.

"We enjoyed the Christmas and everyone made sure they enjoyed Christmas because that's what it is there for," Ballyhale's Joey Holden told RTÉ Sport.

We then got back into training because we knew Ballygunner were a serious outfit. They pushed us to the pin of our collar. We managed to scrape through in muck and wet. And now it's a seriously strong team in St Thomas' who have the likes of Conor Cooney and David Burke in their ranks.

Premier League

There are two games in the top-flight and both will have ramifications on the title race and the make-up of the top four.
