Tomlinson, the NFL's 2006 MVP, had hinted at the prospect Jan. 17 after San Diego's 17-14 loss to the New York Jets in an AFC divisional playoff contest.
"It's mixed emotions," Tomlinson told the newspaper. "I gave the organization everything I have (but) the business part sucks. I won't miss that."
He added he doesn't know when the Chargers will release him.
Tomlinson, 30, who is due a $2 million roster bonus on March 5, has rushed for 12,490 yards on 2,880 carries with 138 touchdowns in nine NFL seasons.
