Fortunately, Jackson's injury isn't that serious.
SAN DIEGO -- Chargers kick returner Darren Sproles will be out for the season with a broken left leg and the team revealed Tuesday that wide receiver Vincent Jackson has been hospitalized since Saturday night with a bruised chest.
Coach Marty Schottenheimer wouldn't expand on Jackson's condition. Jackson was injured in Saturday night's exhibition win over the Green Bay Packers.
"He is still in the hospital but everything seems to be going smoothly and he should be out of the hospital no later than tomorrow," Schottenheimer said. "He has some type of compression injury to his chest, but they expect him to be back and not be any long-term consequence.
Sproles was placed on injured reserve on Tuesday, a day after having surgery on his fractured fibula.
"That's not good news, but that's the way it goes," general manager A.J. Smith said.
"The time frame was too much, three to four months. When you look at it, it just doesn't make sense right now to bring him back. He should have a full recover."
Smith said the Chargers would try to replace Sproles from within first before seeking outside help.
Jackson, who caught three passes for 59 yards as a rookie last year, is being penciled in as the No. 3 receiver behind Keenan McCardell and Eric Parker. Neither McCardell (hamstring) nor Parker (thumb) practiced Tuesday, leaving the Chargers thin at wideout.
The Chargers also waived defensive back Raymond Walls.
