(Santa Clara, CA)  --  Tonight's Seahawks-49ers game is considered the nightcap to a football-filled Thanksgiving.  What some are calling the NFL's biggest rivalry will be renewed at the 49ers' new facility, Levi's Stadium in Santa Clara.  The last contest between the two teams happened last January in the NFC Championship Game, which Seattle won, 23-17.  Kickoff for tonight's game is set for 5:30.
