Ulster captain Iain Henderson has been left out of Ireland's 37-man Six Nations squad, a major selection surprise. The 33-year-old second row, an 85-cap veteran with five titles and two Grand Slams, returned from injury only on New Year's Day. His omission highlights Andy Farrell's preference for a younger forward pack.

Injuries have reshaped Farrell's options. Andrew Porter misses the start with a calf problem, while Mack Hansen is out for the season. Uncapped players Edwin Edogbo and Nathan Doak earn call-ups. Doak likely slots in as third-choice scrum-half, while Leinster's Hugo Keenan retains his place despite not playing since the Lions tour.

Ireland's campaign begins with a huge test against France in Paris on February 5th. They then host Italy, visit England, and finish with Wales and Scotland in Dublin. The squad must navigate these fixtures without Henderson's experience, but Farrell believes his "talented and committed group" can contend for the title after finishing third last year.
