Wide receiver Drew Haddad, signed on Tuesday as insurance because of Parker's condition, may even dress if he can assimilate into the offense.
As for Jackson, the team is happy with his progress in the offense.
"He was hampered because of the injuries but he has worked very hard," head coach Marty Schottenheimer said. "During practice he stands right next to Coach Lofton and listens and watches the routes that are going on by whomever it is in that is in there. He can assimilate information then apply it."
"I'm in (receivers coach James Lofton's) pocket the whole game to try and get out there," Jackson confirmed.
As for Oben, he was unable to practice because of the plantar fasciitis he suffered seven weeks ago. It simply would not get better.
A painful injury to the foot, plantar fasciitis makes it difficult to walk, much less play.
Star running back LaDainian Tomlinson is still sore and will be limited in practice through the week but will play.
The Chargers believed if he would have played more it would have gotten worse so they turned to Turner. With every game crucial at this stage of the game, Tomlinson will be on the front lines when Saturday rolls around.
