England and Bath flanker Sam Underhill is set to miss the Six Nations after having ankle surgery.
The 22-year-old was injured during Bath’s success over Leicester on 30 December and is expected to be out for approximately three weeks.
That would see him skip the tournament, which starts on Friday 1 February and finishes Saturday 16 March.
England travel to Dublin to handle Ireland in their very first match on 2 February (kick off 16:45 GMT).
