Intensely watching his son Max battle the Islanders this week, Tie Domi was temporarily distracted when a fellow Canadian appeared in his Barclays Center suite.
After sharing a few hugs, that Canadian, Justin Bieber, and his entourage quickly took seats next to Domi, the former N.H.L. tough guy, their collective attention focused on No. 16 darting about the ice below wearing the white, red and black of the visiting Arizona Coyotes.
“Go, Max; take off, Max!” Domi urged his 20-year-old son, watching from a bar stool with the hands he had used in 333 N.H.L. fights folded quietly in front of him.
