Robbie Henshaw injury update as Andy Farrell discusses centre's Rugby World Cup future

Robbie Henshaw faces "a couple of weeks" on the sidelines at minimum, according to Ireland head coach Andy Farrell.

The Leinster centre was said to be struggling with a “niggle” on Wednesday, but it has since emerged that he has suffered a hamstring injury and will miss at least two weeks.

Farrell stated that Ireland won’t make a call on Henshaw's fitness or a possible replacement until after their massive Rugby World Cup clash with Scotland on Saturday night.

Henshaw suffered a fitness setback at the start of the tournament when he was a late withdrawal from Ireland’s bench for the 82-8 win over Romania.

He subsequently came on as a replacement in the 59-16 success over Tonga and the 13-8 victory against reigning champions South Africa.

Farrell has made two changes to his starting XV for Saturday's clash in Paris.

Iain Henderson will start in place of James Ryan in Ireland’s second row for Saturday’s crucial match at the Stade de France.

Leinster lock Ryan sustained a hand injury in his country’s 13-8 win over South Africa on September 23 and has been named on the bench, handing a first start of the tournament to Ulster skipper Henderson.

Hooker Dan Sheehan has been preferred to Leinster team-mate Ronan Kelleher and will make his full World Cup debut in the other change to Andy Farrell’s starting XV, while back-rower Jack Conan is back on the bench following injury.

Sheehan came on against the Springboks a fortnight ago for his first appearance since suffering a foot injury in the warm-up win over England on August 19.

Number eight Conan is in line for his first outing since damaging foot ligaments two months ago.

Centre Robbie Henshaw, who has been struggling with a niggle, has been replaced on the bench by Stuart McCloskey, while flanker Peter O’Mahony will win his 100th Ireland cap.

Ireland will secure a place in the quarter-finals with a win or a draw, while defeat will leave them reliant on the scoreline and bonus points gained.

Veteran fly-half Johnny Sexton will captain his side for the fourth successive Pool B fixture following his return from an absence of almost six months due to injury and suspension.

The 38-year-old will be partnered by Jamison Gibson-Park, with the in-form Bundee Aki and Garry Ringrose in midfield and wings James Lowe and Mack Hansen joining full-back Hugo Keenan in the backline.

Sheehan will be sandwiched between provincial team-mates Andrew Porter and Tadhg Furlong, with Henderson packing down alongside Tadhg Beirne.

Centurion O’Mahony, who made his Test debut against Italy in 2012, will continue in the back row with world player of the year Josh van der Flier and Caelan Doris.

The Munster captain is set to become the 10th Irishman to reach the milestone, following Brian O’Driscoll, Ronan O’Gara, Rory Best, Paul O’Connell and John Hayes and current team-mates Cian Healy, Sexton, Conor Murray and Keith Earls.

Conan, Ryan and McCloskey are joined in reserve by hooker Kelleher, props Dave Kilcoyne and Finlay Bealham, scrum-half Murray and fly-half Jack Crowley.
