Ireland expect Robbie Henshaw to be available for World Cup clash with Tonga

Andy Farrell's side launched their Pool B campaign in commanding fashion on Saturday afternoon by dispatching Romania 82-8 in a 12-try rout.

Centre Henshaw was a late withdrawal from the bench due to a hamstring issue, resulting in a recall to the match day 23 for the initially overlooked Mack Hansen.

Prop Dave Kilcoyne (hamstring), hooker Dan Sheehan, and back-rower Jack Conan (both foot) were also sidelined at Stade de Bordeaux.

Ireland appear to have come through their tournament curtain-raiser, which was played in sweltering heat, without any further fitness issues and are optimistic about their ranks being bolstered ahead of their next fixture.

Defence coach Simon Easterby said: "I'd say we haven't ruled anyone out for next week.

"We'll certainly assess more people today and tomorrow.

"It's usually the case that things are maybe flagged 24, 48 hours sometimes after a game as opposed to straight after the night of the game.

"So as far as we are aware everyone came through pretty unscathed, so it was great in that respect in terms of getting players game time in the heat, the conditions.

"We're hopeful that Robbie and others who haven't taken part for whatever reason are available to us next week.

"And that's credit to the guys conditioning the boys and also the medics, the way that they've worked over the last few weeks in particular.

"At the moment we're in pretty good shape."

Farrell's men were forced to come from behind against Romania following the shock of conceding an early score to scrum-half Gabriel Rupanu.

Following temperatures of 36 degrees Celsius on a baking-hot Bordeaux afternoon, Ireland's other three group-stage fixtures will kick-off at 9pm local time.

The Six Nations champions travel to Nantes to take on Tonga this weekend before Paris appointments then follow with South Africa and Scotland.
