Portugal arrives at World Cup 2026 without captain Rúben Dias, who was rested for the opening match against the Democratic Republic of Congo, scheduled for 12 p.m. (local time) in Houston. Coach Roberto Martinez announced on Tuesday that the 29‑year‑old Manchester City defender is still not 100 % after a scare during the friendly against Nigeria.

Why is Rúben Dias missing?

Martinez explained that the centre‑back suffered a muscular discomfort when he fell in the second half of the Nigeria game in Palm Beach, Florida. “He isn’t fit to risk playing at a World Cup. He needs to be at 100 %,” the 52‑year‑old coach said at the press conference in NRG Stadium. The diagnosis shows the player is still in individual recovery, without intensive squad training.

How does his absence affect Portugal’s defence?

With 76 caps and three goals, Dias has been the backbone of the back line since Pepe retired after Euro 2024. His absence leaves a gap that the coach plans to fill with João Cancelo, who has already played as right‑back, and young centre‑back Rui Patricio, who has shown solidity in training. The shift may alter the defensive dynamics, especially against a physical side like Congo.

What to expect in the first game?

Portugal faces the Democratic Republic of Congo at 12 p.m. (18 h in Lisbon) in NRG Stadium, refereed by Abdulrahman Al Jassim of Qatar. The squad has been working on quick transitions and high press in recent sessions, but the lack of Dias could make the back line more vulnerable to aerial balls. The attack, led by Cristiano Ronaldo, still counts on Gonçalo Guedes and João Félix to create chances.

What’s the next challenge?

After the Congo clash, Portugal meets Uzbekistan on 23 June, also in Houston, and closes Group K against Colombia in Miami on 27 June at 7:30 p.m. (00:30 h on 28 June in Lisbon). If the team maintains offensive consistency, Dias’s absence may be mitigated in later games, but the pressure for the captain to return will be huge.

Portugal has until 19 July to fight for the final, staged across the United States, Mexico and Canada. Martinez’s decision to rest Dias reflects a long‑term plan: keep the defensive leader available for the knockout stages of the tournament.
