Iain Henderson the only injury worry Ireland's for Six Nations opener against Wales

Iain Henderson looks set to to be Ireland's only injury worry heading into the first round of the Guinness Six Nations against Wales on Saturday, 5 February.

The Ulster captain has played just once since Ireland's win against the All Blacks in November, picking up a hamstring injury before suffering an ankle knock on his return in December.

The 29-year-old was included in Andy Farrell's squad for the first two rounds of the tournament against Wales and France, and remains in contention for the opener against the defending champions.

In good news, he's likely to be the only injury worry for Farrell to contend with.

Tadhg Furlong, James Ryan, Josh van der Flier, Jordan Larmour and Joey Carbery have reported to camp carrying knocks, but the head coach believes they are all in line to return to training within the next few days.

"To sum it up, we expect everyone bar Iain Henderson to be training fully with us by the end of the week," Farrell told RTÉ Sport this morning at the launch of the 2022 championship.

"Iain Henderson, that's not to say he's out of the Wales game yet, we'll take it day by day and see how we go."

Carbery had looked like he was coming into form before suffering a fractured elbow in November, and Farrell says he's shown real determination to get back in time for the Six Nations.

"Joey has been keeping fighting fit from week two after his injury to his elbow, so he's fit as a fiddle," he
