The Kansas City Chiefs have signed a former San Diego Chargers linebacker to help shore up the middle of their defense.
The Chiefs announced their deal Monday with free agent linebacker Brandon Siler. Terms were not disclosed.
Siler spent the first four years of his career with the AFC West-rival Chargers, where he played 63 games and made 13 starts during the regular season and playoffs. The 6-foot-2, 239-pound Siler was a seventh-round draft pick in 2007 after helping the Florida Gators win the national title.
Siler is considered a run-stuffing linebacker and is expected to pair with Derrick Johnson on the inside.
Sans Siler, San Diego figures to have a new look at the two-linebacker interior of its 3-4 scheme.
Takeo Spikes, a 14-year veteran linebacker, provides experience after starters Stephen Cooper and Kevin Burnett vacated via free agency.
Burnett signed with the Miami Dolphins. Cooper remains unsigned but is not expected to return to the team.
Jonah Mouton, a second round draft pick out of Michigan, and Donald Butler, a third rounder in 2010 who missed his rookie season with a torn Achilles', are among the candidates to help fill the void.
