Retired running back LaDainian Tomlinson, the former TCU and San Diego Chargers standout, told Yahoo.coms Michael Silver that he was approached by new Chargers general manager Tom Telesco and new coach Mike McCoy at the NFL Scouting Combine in Indianapolis and asked if he would consider returning this season to play for San Diego.They said, You can come back and carry it 10 or 12 times a game. Wed like to have you here, said Tomlinson, who declined the offer.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.Tomlinson, 33, left San Diego after the 2009 season and played two more years with the New York Jets. He retired last June as the NFLs fifth all-time rusher (13,684 yards) and third in career touchdowns (162).Briefly • Bears: Oklahoma CB Demontre Hurst, from Lancaster, was signed as an undrafted free agent. • Bills: Tennessee Tech receiver DaRick Rogers agreed to a free agent contract.
