SAN DIEGO (AP) -The San Diego Chargers have released wide receiver Chris Chambers a day after he had a key catch in a 24-16 win over the Oakland Raiders.

Coach Norv Turner said the Chargers released Chambers because of the emergence of Malcom Floyd and the need to sign a linebacker because of an injury to Tim Dobbins on Sunday.

Chambers was demoted Sunday in favor of Floyd, yet still had a big catch in the win over the Raiders, which lifted the Chargers to 4-3.

Chambers was obtained at the trading deadline in 2007 from Miami for a second-round draft pick, and helped the Chargers reach the AFC championship game that season.

His production dropped off dramatically this season.
