If you are in New York City and of Irish descent, there is probably little question where you will be on March 17 of any given year: parading down Fifth Avenue with the occasional stop at a pub for a pint of Guinness or a spot of Jameson’s.

If you are Michael Conlan, your whereabouts on this St. Patrick’s Day — and potentially every one between now and 2021 — will be a matter of public and contractual record. As long as he keeps winning, Conlan, an Irish-born featherweight boxer, will be in the ring at Madison Square Garden, fighting the last bout of the evening.

That is what he will be doing Saturday night, spending his second straight March 17 in a featured bout at the Hulu Theater, the Garden’s 5,600-seat adjunct arena.

“The atmosphere here is unbelievable,” Conlan said. “Just thinking about the last time makes the hairs on the back of my neck stand up.”
