The San Diego Chargers are reportedly set to sign free agent defensive lineman Alfonso Boone today to replace injured nose tackle Jamal Williams, according to the San Diego Union-Tribune and ESPN.com.
A nine-year veteran out of Mt. San Antonio College, Boone started 18 games in seven years with the Chicago Bears, registering 10.5 sacks in that time.
He spent the last two seasons with the Kansas City Chiefs, and reportedly chose to come to the Chargers over the Carolina Panthers due to his familiarity with defensive coordinator Ron Rivera and defensive line coach Don Johnson, for whom he played in Chicago.
Boone comes to the Chargers with experience at defensive end and defensive tackle in a 4-3 scheme, but will see most of his time at 3-4 nose tackle in place of Williams, who was placed on Injured Reserve with a triceps injury. He will likely rotate early on with former practice squad player Ogemdi Nwagbuo.
Due to his versatility, he could also possibly see time at defensive end in a rotation with rookie Vaughn Martin and recent acquisition Travis Johnson as all three work to get acclimated with Rivera's defensive scheme.
