The Giants released Mills (undisclosed) from the active/non-football injury list with a non-football injury designation Thursday, Aaron Wilson of KPRC 2 Houston reports.
Mills began training camp on the active/NFI list due to an injury that remains to be disclosed, and he hasn't practiced since. Last season Mills suited up for all 17 regular-season games with the Patriots, racking up 45 total tackles, one pass breakup and one forced fumble.
