A long list of Washington Redskins missed practice yesterday, but almost all of them are expected to be ready for Sunday's game against Buffalo at RFK Stadium.

The exceptions are running back Kelvin Bryant (knee), defensive tackle Eric Williams (foot) and cornerback Sidney Johnson (concussion). All are definitely out Sunday, and Coach Joe Gibbs said he probably will use one of his two remaining free roster moves to activate Gerald Riggs and place Bryant on injured reserve.

Riggs (sprained arch) ran well again in practice, and if he holds up all week probably will play for the first time in seven weeks.

"It's just a matter of continuing to test it," Riggs said. "It feels good right now."

Tackle Tracy Rocker, on injured reserve with a sprained knee, worked some with the first team defensive line, but Gibbs said he will wait until later in the week to decide whether or not to place Williams on IR.

"It's better today," Williams said, "and I hope it keeps getting better. I'm walking without crutches -- walking kind of funny, but I've always done that. I'm not counting myself out of the playoffs. If that's what they decide, it'll be because they think it's best for the team. I'd like to wait, but I'll understand if they don't."

Other players who didn't practice yesterday: Kurt Gouveia (thigh), Markus Koch (knee), Charles Mann (knee) and Art Monk (knee). Koch likely will miss a second straight game, but trainer Bubba Tyer said he's "running well" and should play against the Eagles in the playoff game Jan. 5 or 6. Resting on Their Laurels?

The Bills (12-3) already have wrapped up the AFC East and home-field advantage throughout the playoffs, and Coach Marv Levy said he might rest his starters more than usual.

"It's important to keep winning, and we'd like to share the best record in the league {if the 49ers lose at Minnesota}," he said. "But we may do a little more substituting than normal. We're going to play everyone that's healthy, and the regular starters will start. I don't have a time frame as to how much they'll play. A guy may start, come out, then go back in." Full Speed Ahead

If Philadelphia (9-6) beats the Cardinals in Phoenix on Saturday, the Eagles will clinch a first-round home game against the Redskins. But even if there's nothing on the line on Sunday, Gibbs said the Redskins will play as they would any game.

"We're going to go full bore," he said. "We're going to play it as hard as we can. I told the team that. We've been working that way as coaches and that's our plan. We're going to do whatever we can to help win the game."
