Leinster set to appoint McNamara as Cullen successor, freeing Nienaber for Springboks return

Leinster are poised to appoint Noel McNamara as their next head coach, with the Irish Times reporting the Clare native will leave Bordeaux-Bègles to succeed Leo Cullen ahead of the 2027/28 season. The move strongly signals that defensive coach Jacques Nienaber will depart the province to rejoin Rassie Erasmus’s Springboks ahead of the 2027 Rugby World Cup in Australia.

Cullen is expected to step down at the conclusion of the current campaign in 2027, and McNamara’s appointment effectively ends speculation linking Felipe Contepomi and Ronan O’Gara to the role. Argentina head coach Contepomi has reportedly ruled himself out of a return to Dublin, while O’Gara, currently at La Rochelle, was always considered an unlikely fit.

Nienaber’s contract at Leinster expires at the end of the season, though a six-month break clause could allow him to return to South Africa even before Leinster’s campaign concludes. Erasmus has shown a consistent appetite for reuniting former colleagues — most recently welcoming Felix Jones back into the Springboks fold after his stint with England — and Nienaber is widely expected to be next.

Securing McNamara represents a significant piece of business for Leinster. The 42-year-old had only recently signed a contract extension with Bordeaux that was set to run through to the end of the 2028/29 season, meaning the two clubs appear to have negotiated an early release.

McNamara’s coaching journey has taken him far from his roots in the Leinster academy system. After working with Glenstal Abbey and Clongowes, he rose through the provincial pathway, managing the academy and later leading Leinster A. His most prominent role in the Irish system came with Ireland Under-20s, where he guided the side to a Grand Slam in the 2019 Six Nations.

Seeking broader experience, he moved to New Zealand with North Harbour before joining the Sharks in South Africa, where he first worked alongside Yannick Bru. When Bru was appointed Bordeaux head coach in 2023, McNamara was among his first recruits.

The partnership has delivered results. Bordeaux finished as Top 14 runners-up in each of McNamara’s first two seasons at the club before claiming the Investec Champions Cup in 2025, defeating Northampton in the final. That European breakthrough has cemented his reputation as one of the most promising coaches in the game.
