UNIONDALE, N.Y. — Pat LaFontaine has always been a popular Islander, though in recent years he has not been seen much at Nassau Coliseum.

Since he left the franchise during the turbulent summer of 2006, after the abrupt departure of Neil Smith as general manager, LaFontaine, the team’s gregarious former center, has primarily concentrated on his charity work and, more recently, working for the N.H.L. as vice president for hockey development and community affairs after a brief job as an executive with the Buffalo Sabres.

Before the Islanders leave for Barclays Center, however, LaFontaine will finally return to Nassau Coliseum, which he called home from 1984 to 1991. A Hall of Famer, he was happy to be invited back by the team owner Charles B. Wang and General Manager Garth Snow to greet fans and be recognized on the ice before Tuesday’s game against the Minnesota Wild.

“I haven’t been in the building for a long time, so I’m excited to see it again,” LaFontaine, 50, said. “I cherish those times and the players I played with. And the Islander fans have always been great. I’m honored to come back to where it all started for me.”
