The Ireland wing Simon Zebo will miss the rest of the Six Nations after breaking a bone in his foot in Sunday's 12-6 Six Nations home defeat by England.

Zebo will undergo an operation on Monday to repair the damage incurred in the 10th minute of a brutal Test in Dublin and has been ruled out for up to 10 weeks.

The prognosis on Jonathan Sexton's hamstring injury was less grave with the Ireland coach Declan Kidney estimating a two-week absence for the Leinster fly-half, who was replaced by Ronan O'Gara after half an hour.

The flanker Sean O'Brien (tight hamstring), the lock Mike McCarthy (knee ligament strain), the centre Brian O'Driscoll (twisted ankle) and the lock Donnacha Ryan (back) also sustained injuries, but have yet to be ruled out against Scotland in two weeks' time.

"Simon will have surgery tomorrow. Jonny will have a scan either later tonight or tomorrow," Kidney said. "It looks like a couple of weeks for Jonny, but it would be wrong to try and second guess the outcome. We'll know more by Tuesday.

"It's been an attritional couple of games and we had a few injuries leading into the tournament but that's the way it goes."
