BOSTON — Move over, Sister Jean. And make some room at the Final Four for Father Rob.

Villanova has a beloved team chaplain, too. And while the 98-year-old nun Sister Jean Dolores Schmidt has been getting international attention for her role with Loyola Chicago during its deep run in the N.C.A.A. men’s basketball tournament, the Rev. Rob Hagan also has a spiritual connection to a Final Four team. He has had a hand in Villanova’s success for more than a decade.

But do not expect any trash talk this week with his fellow basketball-fan-of-the-cloth.

“As someone who is a product of 16 years of Catholic school, I always learned that you respect the nuns,” Father Hagan joked outside Villanova’s locker room Sunday, after the Wildcats earned their second trip to the Final Four in three years with a victory over Texas Tech.

On the TD Garden court minutes earlier, Father Hagan, 53, had stood with his arm wrapped around Coach Jay Wright as Villanova players and staff members climbed a ladder to snip at the nets. Wright and Father Hagan have worked together since 2004, nearly the start of Wright’s tenure with the Wildcats.

Father Hagan said afterward that Wright was confiding in him something the cool, confident coach might not readily admit to the public or the news media.
