Only the New York Giants own a victory over the Redskins at RFK Stadium this season, but Washington hasn't been exactly unbeatable on its home field in recent years.
The Redskins were only 4-4 at home each of the last two seasons, which explains why Washington failed to make the playoffs either year after winning Super Bowl XXII after the 1987 season.
Washington went through a stretch of six seasons (1982-1987) when it went 35-8 at RFK in regular-season play and was 7-1 there in post-season competition.
The Redskins used their last two regular-season moves to activate running back Gerald Riggs and defensive tackle Tracy Rocker from injured reserve.
Four Washington players definitely are out of today's game. Running back Kelvin Bryant (knee), a third-down specialist, and cornerback Sidney Johnson (concussion) will go on injured reserve to make room for Riggs and Rocker. Defensive end Markus Koch (knee) also will be sidelined.
The Skins are leaving defensive lineman Eric Williams on the active roster despite a foot injury that may keep him out of action through the playoffs.
Each playoff team gets an additional free move for each post-season game in which it participates. Washington plans to use its move next week to activate backup quarterback Stan Humphries.
The Bills have one of their five free moves from injured reserve left. Presumably, it will be used to activate cornerback Kirby Jackson, who is eligible to come off injured reserve after today's game.
They also will pick up an additional move for their first playoff game.
Buffalo is looking for a club-first 4-0 sweep of NFC opponents, having beaten the Cardinals, Eagles and Giants, and its first winning record on the road since Kay Stephenson took the Bills to 5-3 in 1983.
Under Joe Gibbs, Washington has a 27-9 record in December the last 10 seasons. So far this month, the Skins are 3-1. Buffalo is 4-0 in December, having beaten the Eagles, Colts, Giants and Dolphins.
When Chicago lost to Kansas City Saturday afternoon at Soldier Field, it left the Bills as the NFL's lone unbeaten on its home field.
