Ireland prop Cian Healy took full part in light training in Cork today, despite reports yesterday suggesting that the Leinster man was struggling for fitness ahead of the World Cup.
The 27-year-old underwent neck surgery on a disc in May and has been recovering ahead of September's tournament. He also suffered hamstring and ankle injuries last season.
Healy's Leinster team-mate Mike Ross told RTÉ Sport: "He's been rehabbing very well. It wasn't a great thing to get but he's been scrummaging this week and we're quite hopeful he'll be in the frame for selection come the World Cup."
Ireland begin their campaign against Canada on 19 September, with warm-up games against Wales, Scotland and England over the next six weeks.
The first of two clashes with Wales takes place on Saturday week at the Millennium Stadium in Cardiff.
"It's a very good warm-up," said Ross. "It was a very intense game during the Six Nations down there and it should put both teams in good stead going into it."
The tighthead also warned against the assumption that players could lower their intensity in a bid to avoid injury.
"You can't really worry about that," he said. "If you go in trying not to get injured, that's when you'll get injured, because you mightn't be going in as hard as you otherwise would and you'd be collided with instead of colliding into."
