Spikes, a first-round draft pick in 1998, has consistently been a leading tackler for the Bengals. But after the team's 2-14 finish last season, Spikes said he hoped to move to a new team and make a fresh start.
He became an unrestricted free agent after last season, and signed an offer sheet Friday with Buffalo. The Bengals had designated Spikes as their transition player, which gave them the option to match any offer he would receive.
Bengal Coach Marvin Lewis, hired during the off-season, had tried to persuade Spikes to stay in Cincinnati.
"I wish him well with his career in Buffalo," Lewis said. "Today is the beginning of a new day in the Bengal organization, and in the shaping of the football team under my direction."
On Friday, the Bengals signed Spikes' expected replacement, free agent Kevin Hardy, formerly with Dallas and Jacksonville.
In Buffalo, Spikes will be reunited with former Bengal coach Dick LeBeau, now an assistant to Bill Coach Gregg Williams, and Tim Krumrie, the former Bengal defensive line coach now in the same job with Buffalo.
The Washington Redskins added one speedy receiver and stepped up their pursuit of another, signing Patrick Johnson and completing an offer sheet for Laveranues Coles.
Johnson signed a one-year contract as an unrestricted free agent from Jacksonville, where he caught nine passes in nine games before his 2002 season was cut short by an abdominal injury. He previously played four seasons in Baltimore, catching a career-high 29 passes for 529 yards in 1999.
The Redskins also have offered Coles, the New York Jets' outstanding young receiver, a seven-year contract worth about $35 million, including a $13-million signing bonus.
Coles is a restricted free agent, so the Jets will have a week to match the offer. If they don't, they will receive Washington's first-round pick.
