The San Diego Chargers have drawn a line in the sand with restricted free agents Vincent Jackson and Marcus McNeill, warning them that their 2010 salaries will be cut deeply if they don't sign their tenders by June 15, the *San Diego Union-Tribune* reported Tuesday.
General manager A.J. Smith told the newspaper that the Chargers sent letters to Jackson, their leading receiver in 2009, and McNeill, their starting left tackle.
Sources told the Union-Tribune that sending letters to the players only would exacerbate the situation and that both are prepared to sit out at least a portion of the 2010 season and potentially all of it.
Jackson's salary would be reduced from $3.268 million to $583,000 if he doesn't sign in the next week. McNeill's salary would drop from $3.168 million to $600,000.
Linebacker Shawne Merriman also has missed offseason workouts, but his tender ($3.269 million) is for 110 percent of his 2009 salary.
