ASHBURN, Va. (AP) _ The Washington Redskins signed Jamel Williams, one of four fifth-round draft picks for the club, to a three-year contract worth $578,000 Monday.

Williams, the leading tackler for Nebraska last season, received an $87,000 signing bonus and will make the NFL minimum base salary of $131,000 in 1997, $164,000 in 1998 and $196,000 in 1999.

The 5-foot-11, 205-pound Williams played linebacker for the Cornhuskers but will compete for a job in the Redskins secondary. Williams was the 132nd overall selection in the draft.

Washington, which opens a four-day minicamp Tuesday, still must sign its top three picks from the draft _ Miami defensive end Kenard Lang, Colorado linebacker Greg Jones and Arizona St. linebacker Derek Smith.

In addition, Redskins general manager Charley Casserly must work out deals with two high-profile players, quarterback Gus Frerotte and defensive tackle Sean Gilbert.

Casserly also is expected to sign Tampa Bay wide receiver Alvin Harper and Oakland quarterback Jeff Hostetler.

In order to stay within the NFL salary cap, some Redskins veterans are expected to be cut this month. Tight end Scott Galbraith, defensive end Sterling Palmer, fullback Marc Logan and defensive back Stanley Richard are among those with uncertain futures.
