On a recent night in Brooklyn, the N.Y.U.-Poly volleyball team won an exciting point in the first game of a match against visiting Purchase College.

No one in the sparse crowd cheered, which made perfect sense.

After all, the home team represented a school that no longer exists.

On Jan. 1, the former Polytechnic University officially became the New York University Polytechnic School of Engineering. Since the merger was legally completed after the start of the academic semester, several Polytechnic sports teams, called N.Y.U.-Poly, were allowed to remain intact through the end of their respective spring seasons.

As a result, dozens of N.Y.U.-Poly athletes are competing in various sports for a school that exists only in their memories.
