LaDainian Tomlinson was diagnosed with a second-degree MCL sprain early this week, a source told It will take at least six more weeks to heal, according to Tomlinson's agent, Tom Condon. "The doctor said this is the type of injury that would seriously hamper LaDainian's ability to cut or push off the leg," Condon said. "His quadriceps muscle had already atrophied one inch. He absolutely can't play in the Pro Bowl and there shouldn't be any question as to why he couldn't go when [the Chargers] played New England."
