The team announced Tuesday that wide receiver Malcolm Floyd, running back Ryan Mathews and offensive lineman Reggie Wells have been moved to injured reserve.
Floyd set a career-high with 56 receptions this season, adding 814 yards and five touchdowns. Floyd's exit from the picture could give Robert Meachem a chance to finish his lost first season in San Diego on a high note.
According to UT-San Diego, Meachem will count a guaranteed $6.875 million against the 2013 cap. He has two catches for 18 yards since Week 7.
