Fresh off a bruising, physical 33-31 victory over the Wallabies in Sydney, Ireland’s management faces a delicate balancing act ahead of this weekend’s clash against Japan at the Newcastle International Sports Centre. While the fixture presents a prime opportunity to rotate squad depth and hand opportunities to hungry fringe players, Andy Farrell’s hand has been forced significantly by a staggering medical bulletin.
With key components of the standard matchday squad completely sidelined, Ireland must field a unique blend of veteran leadership and uncapped potential to navigate the Brave Blossoms’ high-tempo style.
The Brutal Injury Toll from the Australian Battle
The victory in Sydney came at a massive cost. Loosehead prop Jeremy Loughman was forced off with a severe concussion, automatically ruling him out of the weekend action. He joins an already overflowing casualty ward that has stripped Ireland of first-choice stars across the park.
Up front, regular captain Caelan Doris, loosehead anchor Andrew Porter, Ryan Baird, Jack Boyle, Edwin Edogbo, and Paddy McCarthy are completely unavailable. The situation out wide is even more critical; an unprecedented back-three crisis sees Mack Hansen, Tommy O’Brien, and Calvin Nash missing, while frontline fly-half Jack Crowley remains out of action. Combined with James Lowe’s sudden departure from the setup post-URC, this squad rotation is as much about survival as it is about experimentation.
John Fogarty has already taken to the media this week and made a comment on how versatile many of the forwards are when it comes to the front row.
Predicted Ireland Starting XV vs Japan
1. Billy Bohan (Loosehead Prop)
With Loughman entering head injury protocols and Porter back in Ireland, 20-year-old Connacht sensation Billy Bohan is set for a historic international debut. Bohan has been fast-tracked through the pathways due to his immense technical mechanics at the scrum and explosive clearing power. Facing Japan’s low-slung, technically sound packing unit will test his structural discipline early, but the coaching ticket views him as a high-ceiling prospect ready for international exposure.
2. Tom Stewart (Hooker)
Stewart has been impressing for Ulster and has been fulfilling the role of the third hooker for numerous Ireland squads in recent years. With an intriguing contest set for Eden the following week and good minutes under their belts in a green shirt for both Dan Sheehan and Ronan Kelleher, it would make sense to give the next generation a chance at the centre of the scrum.
3. Thomas Clarkson (Tighthead Prop)
Clarkson gets a well-deserved starting opportunity to give veteran Tadhg Furlong a breather. Capable of operating across both sides of the front row in a pinch, Clarkson’s modern mobility makes him perfect for tracking Japan’s horizontal attacking patterns. Scrum coach John Fogarty has raved about his training-ground adaptability, and this test serves as a crucial audition for his long-term position in the tighthead depth chart.
4. Tadhg Beirne (Lock)
Moved from the replacements bench into the engine room, Beirne provides the elite veteran savvy this heavily rotated pack desperately needs. His supreme tactical awareness at defensive breakdowns will be lethal against Japan’s lightning-quick ruck speed. Expect Beirne to disrupt their offensive rhythms single-handedly, anchoring the lineout while acting as an auxiliary playmaker linking the pack to the modified backline.
5. James Ryan (Lock)
Retained in the second row to provide structural consistency, Ryan’s leadership becomes paramount in the absence of Caelan Doris. He will spearhead the defensive hit-and-stick policy required to halt the Brave Blossoms’ lateral scanning. Ryan’s work rate in the unglamorous areas—hitting defensive rucks and securing dirty restarts—will form the absolute bedrock of Ireland’s tight-five dominance.
6. Cian Prendergast (Blindside Flanker)
Having put in a gritty performance against Australia, Prendergast keeps his blindside role to offer relentless energy and physical edge. His massive engine allows him to cover ground effectively, which is vital when containing Japan’s wide-wide attacking loops. Prendergast’s ability to act as an athletic lineout target gives Ireland excellent tactical flexibility when attacking the set-piece inside the opposition 22.
7. Nick Timoney (Openside Flanker)
Handed a golden opportunity to start ahead of Josh van der Flier, the Ulster back-row forward brings a dynamic blend of raw speed and defensive steel. Timoney is elite in the transition space, possessing the acceleration to link play on hard tracks. His link-up play with the half-backs will look to exploit any defensive gaps left by an aggressive, rush-style Japanese defensive screen.
8. Bryn Ward (Number 8)
Ward has been a breakthrough star for Ulster this year. He was in the squad during the Six Nations, but didn’t receive any playing time. Ward is known for his dynamic carrying and wasn’t initially involved in the squad, but was called up due to the injury to captain Caelan Doris. Jack Conan started the first game, and it will be important to keep the Lion fit for Eden Park. We know Conan can make an impact from the bench if needs be.
9. Nathan Doak (Scrum-Half)
Doak made his Ireland debut during the Six Nations against Wales when he came off the bench. The youngster has been key to Ulster’s free-flowing attack and this could be a positive combination with my proposed starter in the 10 jersey, Sam Prendergast.
10. Sam Prendergast (Fly-Half)
Prendergast is short on confidence in a green shirt, but was beginning to get the best out of his game in attack. His kicking to the corner was exceptional and will keep the mauling forwards putting pressure on the Japanese line if given the opportunity. Ireland should have front-foot attacking ball, and this will suit his playstyle well.
11. Zac Ward (Left Wing)
Ward could join his younger brother in the starting team. The former Sevens star has shown power and grit on the wing for Ulster. His lightning speed and strength as a former back-rower could give Ireland an edge in the wide channels. Ireland are suffering from a wing injury crisis, and therefore Farrell will need to give opportunities to those waiting in the wings.
12. Bundee Aki (Inside Centre)
Brought back into the starting lineup to inject raw power, Aki provides the physical baseline required to fix defensive lines. His bruising carrying style will act as a pressure valve, consistently generating gainline success when things get chaotic. Aki’s defensive communication will also be vital in helping his fly-half manage structural spacing out wide.
13. Jamie Osborne (Outside Centre)
Osborne is one of the most versatile backs in Irish rugby at the moment and started on the wing last weekend against Japan. For Leinster for the latter end of the season, he has found himself playing at 12. It would be interesting to see him and Aki play in a rotational centre partnership.
14. Jimmy O’Brien (Right Wing)
O’Brien retains his spot on the right wing, offering supreme positional reliability and elite tactical flexibility. His understated ability to read play early allows him to shut down opposition overlaps before they develop. O’Brien’s silky running lines and smooth left-footed kicking option give Ireland an elegant structural balance across the outer channels.
15. Hugo Keenan (Fullback)
The indispensable structural safety net. Keenan’s flawless positional play and masterclass handling under the high ball ensure Ireland remains completely unshakeable at the back. Against a Japanese side that loves to employ unstructured attacking kicks, Keenan’s elite counter-attacking vision will be the launching pad for turning defensive sets into rapid point-scoring sequences.
