Rotoworld.com reports that San Diego Chargers’ linebacker Shawne Merriman has not one, but two torn ligaments in his knee. The injuries are a threat to Merriman’s career.

Shawne Merriman revealed Saturday that his career could be over. In addition to a torn PCL, Merriman has a torn LCL in his left knee.

His knee requires extensive reconstructive surgery. Perhaps Merriman will chance it and play this year, but that would be foolish. His contract is up after the 2009 season and if he has the procedure, Merriman could try continuing his career afterwards. He’d risk more damage by playing on the knee in 2008. He needs to be removed from IDP draft boards.

That’s quite a reversal from Friday’s report, which stated that Merriman could play this year if he avoids surgery, or miss the entire season if he opts to have a procedure done. This is horrible news for such a young, productive player and while the Chargers’ defense is still quite good, losing Merriman would be a huge blow.
