Updated Calvin Nash set to start for Ireland following Mack Hansen injury

Ireland's preparations for tomorrow’s Guinness Six Nations meeting with Scotland have been disrupted, with Mack Hansen forced to withdraw from the round two game at Murrayfield due to injury.

Hansen had been a doubt for this game earlier in the week after suffering a deep laceration to his left knee in last week’s win against England, however the IRFU have confirmed it's an unrelated hamstring issue on his right leg.

Calvin Nash comes straight into the team on the right wing, where he will win his ninth cap, and first since last summer's tour of South Africa.

The 27-year-old started all five games of last year’s Six Nations campaign while Hansen was also unavailable with a dislocated shoulder.

And Ireland captain Caelan Doris says the Munster man has shown he can step up to Test level.

"There's a lot of trust in Calvin in how he's been with us over the last number of years but also how he's played for much of this year. It should be quite a seamless transition," Doris said.

"He's class. I’ve known him for quite a while, we played together at 18s and 20s as well, so I have seen his quality the whole way, but probably over the last two years in particularly he has kicked on with Munster and took his opportunity incredibly well this time last year over in France.

."There is a lot of confidence, he has trained really well as well over the last number of weeks, so I am looking forward to seeing him tomorrow."

Nash had been unlucky to miss out on selection for last week’s championship opener after his two-try showing in Munster’s final Investec Champions Cup pool game away to Northampton Saints, which coincided with Hansen (above) serving a three-match ban following his comments about referee Chris Busby in Connacht's URC defeat to
