Ireland lock Henderson 'buzzing' ahead of crucial World Cup clash

Having bided his time throughout the World Cup, Iain Henderson admits he's buzzing to a start in Ireland’s crucial Pool B match-up with Scotland.

The Ulster lock started two games in the Six Nations campaign but broke his arm in the round-four win over the Scots.

He made two more starts against Italy and Samoa in the summer but found himself behind James Ryan, Tadhg Beirne and Joe McCarthy as Ireland accounted for Romania, Tonga and South Africa in France.

This time around, as one of two changes to the side, with Dan Sheehan also coming in, that beat the Springboks, he has switched places with Leinster second row Ryan, who had his wrist strapped during the week.

"Obviously to be involved in a game like this, coming down to the crunch time of the tournament, is big," said 77-times-capped Henderson.

"We've been working together hard through the entire tournament and the weeks before that, so we all help each other out as much as possible, everyone pitches in whenever they're required and it's been no different this week.

"It's a huge privilege and honour to start as always, and I'm looking forward to the challenge.

"It's been a good week, an exciting week and it's a big one to be involved in. Delighted with a good week's prep and we're all buzzing for it."

Henderson’s Ulster team-mate Stuart McCloskey (above) is in line for his first taste of World Cup action.

Unused in the three games to this point, the centre comes in after the news that Robbie Henshaw suffered a hamstring injury in training with Andy Farrell speculating that he'll be out for a minimum of two weeks.

McCloskey who was allowed to travel back to Ireland after the birth of his second son, will win his 15th cap if called from the bench to face Scotland in Paris on
