The National Lacrosse League team also released veteran forward Martin Cummings and backup goaltender Chris Seidel.
Zywicki, a native of Nepean, Ontario, spent seven seasons with the Stealth after being the franchises's first-round pick (eighth overall) in the 2005 NLL Entry Draft.
In his time with the organization, the 5-foot-9, 195-pound right-hander established himself as one of the premier players in the NLL and played a significant role in Washington's NLL Championship in 2010.
“Re-tooling our offense for the future is a challenging process,” Stealth general manager Doug Locker said. “Days like this are obviously very difficult. We are thankful for all that Jeff has given to this organization and wish him all the best with other opportunities that come up this season and in the future.”
In 88 games with the Stealth Zywicki scored 394 points (191 goals, 203 assists).
Others released were forwards Peter Jacobs (Hogansburg, N.Y.), Jerome Thompson (Hogansburg, N.Y.) and Mark Negrin (New Westminster, B.C.), transition players T.J. Cowx (Delta, B.C.) and Ryan Johnson (Chilliwack, B.C) and defender Ben McCullough (Brampton, Ont.).
Final cuts to determine the active 23-man roster and three practice-roster spots must be made by Thursday.
The Stealth begin their fourth season of play in Everett on Jan. 5 at Comcast Arena against the defending NLL champion Rochester Knighthawks
