Chargers may miss key weapon

Just as Philip Rivers had all his top receiving options healthy, a potential problem arises.

Star receiver Vincent Jackson did not practice all week with a groin injury and he is listed as questionable to play Saturday at Detroit. The team is worried he may miss the game, although the final decision will be made at game time.

The Chargers are fighting to stay alive in the playoff race. San Diego’s offense has dealt with many injuries this season, but it has been clicking in recent weeks with players like Jackson, receiver Malcom Floyd and tight end Antonio Gates healthy. After struggling for the first 10 games, Rivers has flourished for the past month with a healthy receiver crew.

Jackson has 56 catches for 1,038 yards and eight touchdowns. He is 13 catches, 132 yards and two touchdowns from establishing new career highs.

Meanwhile, linebacker Travis LaBoy is out for San Diego with a knee injury and defensive tackle Antonio Garay is questionable with a toe injury.
