Donald Stephenson and Geoff Schwartz might as well consider themselves quasi starters the way the two Chiefs offensive linemen have been pressed into service this season.
In an ideal world, Stephenson is supposed to be the backup offensive tackle, Schwartz the reserve offensive guard.
But injuries to just about everybody on the Chiefs' already suspect offensive has resulted in each of them playing in every game this season.
They could be pressed into service Sunday against San Diego,
Right tackle Eric Fisher has been dealing with a shoulder injury and right guard Jon Asamoah some calf spasms and a shoulder injury of his own.
If either of them can't start, it will be up to Stephenson and Schwartz to fill the void.
