Remember when the Los Angeles Chargers had a dynamic receiving duo? It wasn't very long ago, when the team employed Keenan Allen and Mike Williams. Allen was traded to the Chicago Bears and Williams was released due to cap constraints last offseason.

EL SEGUNDO — Chargers wide receiver Mike Williams told the team he planned to retire rather than continue his standout NFL career after eight seasons, a club spokesman confirmed while the opening day of training camp was underway Thursday morning. Williams spent seven of his eight years in the NFL with the Chargers.

Mike Williams is hanging his cleats up for good. The Los Angeles Chargers wide receiver informed the team of his plans to retire from the NFL on Wednesday night, a person close to the situation told USA TODAY Sports' Tyler Dragon.
