Tomlinson, who will turn 34 in June, told Yahoo! Sports that new Chargers general manager Tom Telesco and first-year coach Mike McCoy met him at the NFL scouting combine in February and "they asked me to come back and play."
"At first I thought they weren't really serious, but they kept talking about it, and I realized it was real. They said, 'You can come back and carry it 10 or 12 times a game. We'd like to have you here,'" he told Yahoo!
Tomlinson, the Chargers' all-time leading rusher (12,490 yards), told Yahoo! that he never seriously considered returning to play for the team in 2013, however.
"... When I made the decision to walk away, I wrestled with it long and hard, and I knew it was final. Once I retired, that was it. My mind is in a different place. Mentally, going back would have been too hard," he told the website.
In 11 seasons, Tomlinson rushed for 13,684 yards, fifth all-time, and scored 162 touchdowns, third-most ever. His 145 rushing touchdowns are second-most in history. He also passed for seven touchdowns. Chargers president Dean Spanos said last year that Tomlinson's No. 21 will never be worn by another San Diego player.
