Quill battled through injury during his time at the academy and after a few months he returned from London to link up with his former club, Dolphin RFC where he put together an impressive string of performances.[6]
Quill signed with London Welsh of the RFU Championship in February 2014.[7] He was released by London Welsh at the end of his first season with the club after helping them achieve promotion to the Aviva Premiership.[8]
Quill played for the Ireland Schools team. Although Quill is Irish, he qualified to represent the United States through his American mother.[9]
Having impressed during his time with Boston RFC, Quill was called into the USA squad for the 2012 Autumn internationals during which he made his debut against Russia.[10]
Quill was selected for the USA Eagles's 2015 World Cup squad.[11] He was also selected for the USA Eagles' 2019 Rugby World Cup squad, and was sent off in the opening defeat (45-7) against England, after delivering a shoulder to the head of Owen Farrell, the first red card of the tournament.[12] Following the 2019 World Cup Quill retired from international rugby.[13]
