With important Magners League and Heineken Cup fixtures between now and then, Ulster have recruited experienced international Emerick to provide cover for the outside backs.
Emerick has extensive experience of European rugby having played for both Newport Gwent Dragons and Italian club side Parma and has been capped for the USA Eagles over 30 times, most recently in the summer's Churchill Cup campaign. He will link up with Ulster next week.
Ulster Rugby is also delighted to announce that Adam D'Arcy, the Australian fullback who has been on trial with the club has agreed a one year contract. D'Arcy made an impressive debut against Leeds last weekend and his addition completes Ulster's professional playing squad for 2010-11.
