Ulster have added to their back-row strength by signing Irish-qualified New Zealander Sean Reidy and Lansdowne player Charlie Butterworth.

Reidy, 25, has signed a short-term deal with the province after playing for the Counties Manukau Steelers in his native New Zealand.

Wicklow man Butterworth, 23, has agreed a one-year deal.

Ulster's new arrivals for next season also include South African duo Louis Ludik and Wiehahn Herbst.

The Province currently have three back-row players on tour with Ireland in Argentina, while Roger Wilson played for a World XV against South Africa last weekend. Ulster also have Nick Williams on the books.

However, Stephen Ferris is no longer available to Ulster following his retirement last week.
