Shanagher is the son of Irish rugby player Denis Shanagher Sr, who captained Bective Rangers to a Leinster Cup title prior to emigrating to the United States, where he became an influential referee and rugby administrator.[1]
A center, Shanagher captained Stanford University in varsity rugby, then played club rugby for San Francisco and Bay Area Touring Side (BATS). He gained nine caps for the United States during the 1980s and was flown to Australia in 1987 as an injury replacement for Mike Caulder at the Rugby World Cup.[2]
