Melvin Gordon's agent, Damarius Bilbo, requested a trade last week for his client after the Los Angeles Chargers refused to increase their initial offer of approximately $10 million per year, Bilbo told ESPN's Josina Anderson on Thursday.
However, Chargers general manager Tom Telesco did not give Bilbo permission to seek trade partners, Anderson added.
Gordon's party publicly called for either an extension in line with the top running backs in the NFL or a trade. The former first-round pick has one year and $5.6 million left on his rookie contract.
The tailback was a no-show for the start of training camp on Wednesday and recent reports indicate that his holdout threatens to carry over into the regular season.
Gordon's request of $10 million per season would place him fourth among running backs behind Todd Gurley, Le'Veon Bell, and David Johnson. Dallas Cowboys ball-carrier Ezekiel Elliott is also holding out for a deal that could top Gurley's.
