Fitzgerald previously spent four seasons with the NASL side prior to joining New York City FC on Dec. 11, 2014.
The 27-year-old made a pair of appearances for the Club during their first-ever preseason; he came on as a second-half substitute in the 2-0 win over St Mirren on February 10 and Fitzgerald started and played the first half in the 2-1 loss to the Houston Dynamo in the Carolina Challenge Cup on February 24.
Fitzgerald played collegiately at Wake Forest University and is among the university’s all-time goalkeeper leaders in minutes played, goals against average, save percentage and saves. He had an Atlantic Coast Conference-best 81 saves his senior season.
New York City FC returns to the field against Real Salt Lake on Saturday. Kickoff from Rio Tinto Stadium is 10 p.m. EDT.
