THE SIDELINES : Williams Quits City Hall for N.Y.

Reggie Williams, who parlayed his fame as a Cincinnati Bengals linebacker into a seat on City Council, says he is resigning the post to take a job with a new football league’s New York team.

“There are some risks to this, and that’s part of the appeal,” said Williams, who has been on the council since May, 1988.

Williams, 36, said he will become general manager of the New York franchise in the 10-team World League of American Football, which begins play in March. Williams was appointed to fill the City Council seat of former Mayor Arnold Bortz, who resigned to pursue business interests. Williams was re-elected in November, 1989, and retired from football after last season, his 14th with the Bengals.
