We have just learned the assignments for the Wild Card weekend. Officials are listed with their uniform number, years experience (including this season), the crew each official worked with in the regular season (by the referee’s name), college, and outside occupation. All times are Eastern.

Three alternates are assigned to each game: one is designated for the offensive backfield (a referee or umpire), one is on the line of scrimmage (head linesman or line judge), and one is a deep position (side judge, field judge, or back judge).

Updated to reflect the swap of head linesmen in Ravens and Redskins home games (story).
