San Diego running back news

There will likely be daily running back news coming out of San Diego as the Chargerslook to replace LaDainian Tomlinson after his release.

There were some interesting developments Saturday morning:

The Santa Rosa Press Democrat believes San Francisco could make a run at San Diego's change-of-pace back Darren Sproles, who is expected to hit free agency. Sproles, a dynamic rusher, receiver and return man, would fill several needs for the 49ers.

The Chargers want Sproles back but not at an enormous price. The two sides will continue to talk about a long-term deal.

• If Sproles were to leave, some speculated San Diego native Reggie Bush could replace him. Scratch that possibility.

ESPN.com reports that the Saints will keep Bush in 2010. There had been some thought that New Orleans would cut the speedy Bush.
