SAN DIEGO -- San Diego star running back LaDainian Tomlinson has a "possible abdominal strain."
Tomlinson, who has three touchdowns in San Diego's rout of Denver, went to the locker room but is back on the field. It was announced he may return.
But his backup Darren Sproles is playing well and with the game well in hand midway through the fourth quarter, Tomlinson will likely sit for the rest of the game.
